MDaemon Server 8.0 正式版

MDaemon Server 8.0 正式版 Description:
美国时间2004年4月12日，Alt-N发布MDaemon Server 8.0正式版，以下为官方发布说明：

-----------------------------
MDaemon 8.00 - April 12, 2005
-----------------------------

SPECIAL CONSIDERATIONS
----------------------

  o All or parts of this file may not be localized.

  o Your AntiVirus update schedule file (\App\AVSchedule.dat) was renamed to
    \App\AVSchedule.dat.old so that a new set of default update times could
    be put in place.  The new defaults randomize the times that updates take
    place but schedule only a single update per day.  You can return to your
    old update settings by renaming \App\AVSchedule.dat.old to
    \App\AVSchedule.dat if you wish (restart MDaemon after renaming the
    file).

  o This version creates Calendar, Contacts, and Task folders for each user
    and a Contacts folder for each domain during the installation.  If these
    folders already exist they will be renamed to Old Calendar, Old Contacts,
    and Old Tasks.  See the IMPROVED COLLABORATION SUPPORT section below for
    more details.

  o MDaemon requires activation of your registration key.  The goal of the
    activation system is to combat piracy and protect the interests of
    legitimate customers.

    Immediately after MDaemon loads it will launch the Activation Wizard
    which will walk you through the simple process of activating your
    registration key.  You can activate in a fully automated fashion or
    manually if you prefer.  The process takes only a few seconds.  
    
    Activation verifies that the key you are using is legitimate.  It also
    ties your registration information to your computer using the MAC address
    of your Network Interface Card making it impossible for others to
    illegally use your registration key.  No personal information about you
    is required or transmitted.  Reactivation is required only if you change
    out your Network card.  The 'Help | Activate your registration key...'
    menu selection will launch the Activation Wizard should you need to do
    this in the future.  
    
    Multiple activations are allowed however this is for customer convenience
    only and should not be considered license to violate the EULA.  
    Registered users have 30 days in which to activate.  Activation is
    required in order for MDaemon to function.

    For a more detailed description of activation see:
    http://www.altn.com/Activation/faq.asp

  o This version of MDaemon requires WebAdmin 3.10.  You can obtain WebAdmin
    3.10 from http://files.altn.com/WebAdmin/Release/

  o Please note the evolution of the old MDaemon GroupWare product into the
    new Outlook Connector for MDaemon.  This name change is reflected in
    numerous places within the MDaemon GUI and documentation.  To read more
    on this check out this partner newsletter:         
    http://files.altn.com/static/images/partners/press/newsletters/NL-200501.pdf

  o The default automatic spam filtering IMAP rule created for each account
    via the Spam Filter's 'Automatically filter spam messages into user's
    IMAP spam folder' was changed.  The rule used to merely check for the
    existence of the X-Spam-Flag header within each message.  This was found
    to be not sufficient because some external SpamAssassin enabled software
    places 'X-Spam-Flag: No' into messages.  So, the rule was changed to
    check for 'X-Spam-Flag: Yes' rather than just the existence of the header
    itself.  To change the rule for all your accounts uncheck the 'Auto-
    matically filter spam messages into user's IMAP spam folder' option and
    follow the instructions.  This will remove the old rule from each of
    your accounts.  Then recheck the same option to build the new rule for
    each account.

  o Some of the WCML tags have been changed.  Your custom WorldClient
    templates will need to be updated.

  o If you are using the composite log check your settings.  They will need
    adjustment because a new log for Outlook Connector activity has been
    added.

  o Using the Content Filter's "Copy the message to specified user(s)" action
    with a mailing list as the target of the action can lead to the following
    problem:  if the list is keeping a digest then the digest will NOT get a
    copy of the message.  This limitation will be addressed in a future
    version.

  o Older versions of ComAgent will no longer be able to sync contacts with
    MDaemon 8.  To regain this capability your users must update to ComAgent
    8.

  o The WhoWhere and InfoSpace public LDAP servers no longer appear to be
    operating.  Therefore the installer will rename your AddrLookup.ini file
    to AddrLookup.old before installing a new version which removes these
    entries.  If you have added custom LDAP servers for your WorldClient users
    (including LDaemon for example) you can reconfigure them by editing the
    new AddrLookup.ini file (remember to start numbering at 1 ex: [LDAP1]).

MAJOR NEW FEATURES
------------------

  * IMPROVED COLLABORATION SUPPORT (MDaemon PRO only) *

    Collaboration support within MDaemon/WorldClient has been completely re-
    written and vastly improved.  From within WorldClient you can now more
    easily and attractively create appointments, schedule meetings, and work
    with address books.  For the first time, recurring appointments are
    fully supported.  Also, appointments are more elaborate with many more
    fields available to describe them than were possible before.  Internally,
    contacts, calendars, and task data are stored as IMAP folders within each
    user's root mail directory.  Users can use WorldClient or Microsoft
    Outlook* to access these folders and control what other users have access
    to these folders.  All WorldClient themes (and especially Lookout) have
    been modified with new templates which present contact, calendar, and
    task folders in a more logical and attractive way.

    MDaemon supports and automatically creates domain-wide contact, calendar,
    and task folders which all domain users will have access to via
    WorldClient or Microsoft Outlook*.  By default, users of a domain will
    have full access to add, edit, and delete items in these folders.  You
    can easily change this through the MDaemon GUI if you desire to restrict
    access to these folders.

    The new collaboration system within MDaemon is completely IMAP/ACL based
    with data stored in XML and RFC/TNEF format.  This allows seamless
    integration with the Outlook Connector for MDaemon plug-in used by     
    Microsoft Outlook.  Granting other users access to your folders can be
    achieved via WorldClient or Outlook*.

    MDaemon no longer maintains a single address book for all domains.  
    MDaemon keeps address books on a per-domain basis now.  Any other address
    books will have to be created and maintained by you (if you want them).  

    *Requires Outlook Connector for MDaemon (see http://www.altn.com).

    IMPORTANT:

    If you are upgrading to MDaemon 8 from a previous version, the
    installation process will automatically convert each users private
    address book (their addrbook.xml file) to the new Contacts folder in
    their root mail directory.  Also, each users calendar information will
    be migrated from their old Calendar.mrk file to the new XML format
    within the new Calendar folder in their root mail directory. Finally,
    each domain's public address book will be converted and placed into
    the domain's Contacts public folder.  None of the original files are
    deleted by this process.  You can run \App\MD3Conv.exe to forcibly
    migrate the calendar and contact data for any user (or all users) as
    needed. Just run it once with no command line arguments for instructions.

    If the migration process finds a Calendar or Contact folder that already
    exists for a user or domain it will rename that folder to Old Calendar
    and Old Contacts.  Access control is preserved when folders are renamed.

  * DOMAINKEYS SUPPORT (MDaemon PRO only) *

    MDaemon is now DomainKeys enabled (http://antispam.yahoo.com/domainkeys).
    DomainKeys is a specification intended to provide email sender verifica-
    tion.  MDaemon can both sign outgoing and verify incoming emails using
    DomainKeys.

    MDaemon's GUI now has a DomainKeys tab, DomainKeys logging options, and
    a configuration screen on the Security menu where you can setup your
    DomainKeys properties.

    MDaemon includes the ability to generate private and public keys suitable
    for use with the DomainKeys specification.  A button within the new
    DomainKeys GUI will allow you to create keys.  By default, keys are
    generated with a bit depth of 1024 bits which should be very secure.  A
    default selector ('MDaemon') and a default public and private key are
    created automatically on startup (if they do not already exist).  All
    keys are unique and are never the same from one site to another.

    MDaemon supports multiple selectors and key pairs.  Selectors and keys
    are stored under the \MDaemon\Pem root folder in the following way:

    \MDaemon\Pem\<Selector>\rsa.public - public key for this selector
    \MDaemon\Pem\<Selector>\rsa.private - private key for this selector

    All keys are stored in PEM format.

    Only messages which are sent to non-local users using SMTP AUTH will
    be signed.  Mailing list messages are never signed.

  * IMPROVED ANTISPAM - SPAMASSASSIN 3.0 (MDaemon PRO only) *

    MDaemon now includes SpamAssassin 3.0.  This new version of SpamAssassin
    includes many upgrades and improvements.  For a complete list of changes
    see http://www.spamassassin.org.

    How the subject tag is specified on the Heuristics tab within the Spam
    Filter GUI was changed.  SpamAssassin no longer supports a key to turn
    subject modifications on and off.  Instead, the existence of a subject
    tag determines whether one is used or not.  As a result, please check
    this tab and make sure the subject modification is to your liking. Also,
    the _HITS_ tag in SpamAssassin 3 does not pad the score with leading
    zeros.  This caused us a sorting problem here so you might want to look
    at your subject tag and change _HITS_ to _SCORE(0)_ which will left pad
    with a leading zero.

    SpamAssassin 3 doesn't come configured to use the JP list for SURBL so we
    added a rule for it to 80_MDaemon_scores.cf.  Also, the default SA 3
    scores for SURBL hits were much lower than what we previously used with
    MDaemon so I put the old SURBL scores in 80_MDaemon_scores.cf.  Adjust to
    your liking or delete the lines to use the SA 3 defaults.

    New default Bayesian scoring has been added to 80_MDaemon_scores.cf.  In
    the future this file will always contain the default scores for Bayesian
    rules.  You may wish to consider deleting the various 'score BAYES_xx'
    lines from your local.cf file in order to use the new defaults.  The new
    defaults are much lower than previous versions of MDaemon but then so are
    the defaults within SpamAssassin 3 itself.  

  * CUSTOM PLUG-IN SUPPORT (MDaemon PRO only) *

    MDaemon can integrate custom built plug-ins.  See \Docs\Api\Plugins.txt
    for more details.

  * HASHCASH "PROOF-OF-WORK" SUPPORT (MDaemon PRO only) *

    MDaemon is now able to generate hashcash stamps.  Hashcash is a form of
    electronic postage designed to help verify that the sender of an email
    message invested sufficient effort in order to do so.  Effort is
    measured in terms of CPU use.  Now that hashcash verification is support-
    ed by SpamAssassin 3.0, the stamps generated by MDaemon's hashcash
    system and inserted into outgoing messages will have a real impact
    on lowering the false positive rates when your users send mail.  A new
    screen was added to the Spam Filter properties to configure hashcash
    settings.

    In order for stamps to be generated and inserted into messages they must
    not be list messages and must be either FROM or TO an address listed in
    HCMint.dat file.  You can configure all this from within the Hashcash
    properties in the GUI.

    In order to honor hashcash stamps for incoming messages your domains
    must be listed in the \SpamAssassin\Rules\80_MDaemon_Hashcash.cf file.  
    The installer has already enabled all users of your primary domain for
    this.  To see how it is done for other domains just open the file with
    notepad and read the instructions there.

    For more information on HashCash and to support the HashCash concept
    visit http://www.hashcash.org/.  

  * IMPROVED QUEUE MANAGEMENT *
  
    Added a basic queue management system directly into the main MDaemon GUI.
    This mimics some of the MDStats functionality but in a more integrated
    fashion.  Double clicking a queue on the stats pane window will open the
    MD GUI to this new queue management system rather than MDSTATS.  You can
    still right click and select to view queues using MDSTATS if you want.

  * IMPROVED ERROR MANAGEMENT - HOLDING QUEUE *

    MDaemon now has a new queue - the 'holding' queue.  The purpose of this
    queue is to receive any messages which cause software exceptions during
    AntiVirus, AntiSpam, or Content Filter processing.  If a software error
    occurs during the processing of messages the messages will be moved into
    the holding queue and not delivered.  When messages are placed into the
    holding queue they stay there until the administrator takes some action.
    
    A button and menu option to process the holding queue were added to the
    GUI.  Processing or 'Re-Queue'ing the holding queue content will shuffle
    all the messages into either the remote or local queues for processing.
    If the error which caused the messages to be placed into the holding
    queue still exists the messages will just be routed right back into the
    holding queue.  'Release'ing the content of the holding queue will
    deliver the problem messages regardless of any error which might occur.
    A warning box is provided when 'Release'ing the queue since doing so
    could potentially introduce messages into the mail stream which did not
    properly filter through the Content Filter, AntiSpam and/or AntiVirus
    engines.

    A system for configuring notifications related to the holding queue was
    added to the Queues menu selection in the GUI.  Note that if these
    notifications themselves cause software errors they may not be delivered
    to remote recipients, but local recipients will work fine.  Notifications
    are sent to the configured parties at MDaemon startup, the first time a
    message is placed into the holding queue, and once every XX minutes
    thereafter  until either the queue is emptied or the notification
    mechanism is switched off.

    Note: when the SpamAssassin.dll file fails to be initialized or is other-
    wise hosed (which can happen from time to time) MD will no longer switch
    off the Spam Filter.  Also, the message normally sent to postmaster when
    this occurs has been changed to only send if the holding queue mechanism
    is inactive.

  * IMPROVED ANTIVIRUS INTEGRATION *
   
    MDaemon can now scan incoming messages for viruses during the actual SMTP
    session.  A new switch was added to the Security|AntiVirus GUI to govern
    this behavior.  This switch is enabled by default.  This feature requires
    MDaemon AntiVirus.  If a message is found to be infected the message is
    immediately refused and can not be accepted.  This feature can and will
    slow down the processing rate of the SMTP server.  Messages larger than
    MAX_SIZE will not be scanned during the SMTP session.  MAX_SIZE defaults
    to 10MB and can be set by editing the following in the CFILTER.INI file
    with Notepad:

    [VirusScanner]
    InlineSMTPMax=10 (value in megabytes)

    The SMTP-(in) log will show the result of AV processing.  The possible
    results you might see are:

    1) the message was scanned and found infected with a virus
    2) the message was scanned and no virus was found
    3) the message could not be scanned (usually because a ZIP or other type
       or attachment could not be opened/accessed)
    4) the message could not be scanned (it exceeds the max size limit)
    5) an error occurred during the scan     

  * IMPROVED OUTLOOK CONNECTOR INTEGRATION *

    MDaemon now has an Outlook Connector tab in the main GUI.  This tab
    displays all the IMAP interaction between the MDaemon server and Outlook
    Connector clients.

    A separate log file is also created which will track all IMAP activity
    between the server and the OC clients.  Options have been added to the
    logging settings to enable/disable this logging.  The composite log file
    settings also has the same.

    Several small changes were made in the GUI to facilitate the evolution
    of our Outlook Connector product.  These changes include modifications
    to the verbiage on the Setup configuration screens.  Also, the on/off
    switch was removed from the main list of servers on MDaemon's main screen.  
    Outlook Connector support can be turned on/off via the Setup menu.

  * IMPROVED LDAP QUERIES FOR GATEWAY USERS (MDaemon PRO only) *

    It is now possible to specify multiple LDAP configurations for your
    gateway domains.  LDAP is used to verify that accounts actually exist
    before accepting messages bound for gateway domains.  To specify extra
    sets of LDAP parameters you have to setup your first set using the GUI
    as normal.  Then manually edit the GATEWAYS.DAT file using notepad.  
    Create a new set of keys that look like this:
    
    LDAPHost1=<host name>
    LDAPPort1=<port>
    LDAPBaseEntry1=<base entry DN>
    LDAPRootDN1=<root DN>
    LDAPObjectClass1=MDaemonContact
    LDAPRootPass1=<password>
    LDAPMailAttribute1=mail

    Note that each key ends with '1'.  You can add a third set of parms by
    creating another set of keys which end with '2', then '3', and so on.

    When the LDAP queries take place, MDaemon will perform multiple LDAP
    checks in sequence, if necessary, for a match.  If an error or a match
    is found no further checks are performed.

CHANGES AND ADDITIONAL NEW FEATURES
-----------------------------------

  o When messages are released from the Spam Trap the MTA thread will strip
    the subject text of all data found between the first [ and ] characters.  
    So, if you change the default Spam Filter 'Subject tag' text, be sure you
    enclose your changes in [ and ] chars if you want this tag automatically
    removed.

  o SPF processing is now enabled by default and has a new option to check
    the FROM header (previously it could only check the SMTP envelope
    sender).  The SPF configuration screen in the GUI has a check box to
    enable this (it is disabled by default).  Note that if the address
    checked during SMTP session is the same as that taken from the FROM
    header the duplicate check will be skipped to save CPU and so on.

  o SPF GUI has a new switch to cause MDaemon to send all forwarded mail
    using the email address of the account forwarding the mail.  This helps
    reduce problems associated with forwarding.  Normally, forwarded mails
    are sent using the email address of the original sender and not the
    email address of the account actually doing the forwarding.

  o MDaemon will no longer generate route slips and send mail to itself via
    SMTP when forwarding to local recipients.  If you must have forwarded
    mail being delivered to a local recipient filtered through the SMTP
    engine then manually specify localhost or 127.0.0.1 in the account's
    'Forward mail to this host' field.

  o Accountprune has the following default settings for "SkipAutoPrune":
    Public IMAP folder - "SkipAutoPrune=Yes"
    Non Public IMAP folder - "SkipAutoPrune=No"

  o The default ACL access rights to the Bayesian Learning root folder for
    new installations was changed from 'lrswi' to simply 'lr' to prevent
    users from moving messages into the root folder by default.

  o Set the following switch in the MDaemon.ini with Notepad if you would
    like MDaemon to return messages that receive 'no records of the requested
    type' during MX record lookups:
    [Domain]
    NoAnswersImmediateReturn=Yes

  o Set the following switch in the MDaemon.ini with Notepad if you would
    like MDaemon to return messages that receive 'no records of the requested
    type' during A record lookups:
    [Domain]
    ANoAnswersImmediateReturn=Yes

  o Several small tweaks were made to the Spam Trap summary report including
    a link to WebAdmin's spam trap manager page (requires WA 3.10 and you
    must provide a link to WebAdmin in WorldClient's Domain.ini file here:

    [Default:Settings]
    WebAdminURL=<link including port value if necessary>

  o By default, MDaemon uses the account's mailbox value as the 'logon' parm
    when using dynamic authentication with Windows to verify that an account
    exists.  Sometimes this parm does not match an actual Windows account
    and so the verification fails.  If you would like to use a different
    logon for an account you can edit the account's HIWATER.MRK file which
    you will find in his/her root mail directory and add the following key:

    [Settings]
    NTLogonName=<whatever you want>

    From then on MDaemon will use this value when performing dynamic
    authentication on the mailbox in question.

  o It is no longer possible to directly specify the config file backup
    directory so the option was removed from the Misc. Options GUI.  
    Backups are automatically placed in the \MDaemon\Backups\ directory.
    If you want to specify a different location you can change the
    following parm in MDaemon.ini using Notepad:

    [Directories]
    ConfigFileBackups=<path>

  o The SMTP engine will only prune addresses from lists if the result of a
    delivery attempt to the list member nets a 550-554 result code.  If you
    want to completely disable pruning during the SMTP stage for a list open
    the list's .GRP file with notepad and add this line near the top of the
    file:

    ; SkipSMTPPrune = Y

  o The term "Spam Blocker" has been removed from MDaemon and replaced with
    the more appropriate term "DNS Blacklists" which is more accurate and
    reduces confusion between RBL processing and the Spam Filter.

  o By default, MDaemon will now reject messages to over quota recipients at
    the RCPT stage rather than after the message is received.  If you would
    like to change this you can edit the following switch in the MDaemon.ini
    file:

    [Special]
    TestQuotaAfterDATA=Yes (default NO)

  o MDaemon no longer needs its own SURBL configuration file or GUI dialog.
    These were needed when older versions of SpamAssassin were being used.
    The 80_MDaemon_surbl.cf file has been deprecated as has the SURBL
    configuration screen in the Spam Filter properties.  SURBL is now an
    integrated part of SpamAssassin and can be configured by editing the
    25_uribl.cf file in the \SpamAssassin\Rules directory (not recommended).

  o MDaemon now defaults to using 1/2 the outbound session threads when send-
    ing messages from the retry queue.  This frees up 1/2 of the threads for
    processing regular mail.  If you would like to have MDaemon use all the
    outbound threads when processing the retry queue (as it has done in the
    past) edit the following key in MDaemon.ini and set it to ZERO:

    [Sessions]
    MaxRetry=0

  o By default MDaemon will no longer accept messages sent from addresses
    on the suppression file.  In the past, the default in many cases was
    to accept the message, process it, and send to the bad queue.  The
    suppression file editor will now allow the "Refuse during SMTP" option
    to be enabled under the "All Domains" root.  This is the new default.  If
    you would like to selectively accept/refuse on a per-domain basis, then
    you need to disable this option under the "All Domains" root and enable
    it under the individual domain nodes.

  o When messages are submitted to list digests MDaemon will scan the
    message and attempt to include only the first text/plain part of the
    message to the digest.  Other message parts are not included in the
    digest (including HTML parts).  If the message does not have a
    text/plain part or if the messages is not multipart/alternative or
    multipart/mixed then the whole message will likely be included in the
    digest (minus any MIME attachments).

  o MDaemon now supports the forth-coming "Authentication-Results" header
    (this spec is still in draft stage so some changes might be coming).
    This new header is planned for use with AUTH, SPF and DomainKeys as the
    preferred method for communicating authentication results to MUAs.

    This header is written for locally delivered mail only.  If you do not
    wish MDaemon to use this header at all set the following switch in
    MDaemon.ini:

    [Special]
    WriteAUTHHeader=No (default Yes)

  o Added switch to the SMTP AUTH GUI that exempts messages to local
    accounts from the requirement that messages sent from local accounts
    must be AUTH'ed.  This switch is enabled by default which is a change
    from previous versions.

  o You can specify new settings in the AV scheduler.  By selecting 'Random'
    for the minute value MDaemon will do the update at a random time during
    the hour.

  o Lots of SPF related logging can be cut by setting the following switch
    in the MDaemon.ini file (this switch causes SPF to only log matches):

    [ReverseLookup]
    SPFLogOnlyMatches=Yes (default No)

  o The checkbox which creates Calendar, Contact, and other domain-level public
    folders was moved from the Domain editing screen to the Public Folder
    editing screen.

  o It is no longer possible to use a period char as the IMAP folder delimiter.
    Doing so causes internal havoc to the code.  So, on startup MDaemon will
    change the default delimiter to the default char '/' if it is currently a
    period char '.'

  o Added WorldClient INI file settings that allow admins to disallow users to
    view calendars and tasks as well as not add new calendar, task or contacts
    folders. Set the following INI values under the [User] section of the
    User.ini file or in the domains ini file to disable the various
    functionality:
    
    EnableCalendar=No
    EnableTasks=No
    CanCreateContactsFolder=No
    CanCreateCalendarFolder=No
    CanCreateTasksFolder=No

  o The active AV update schedule will be dumped to the System log at startup
    and whenever the schedule is changed using the GUI.

  o WorldClient will automatically select the Pocket PC theme for any Windows
    CE devices which connect.

  o Added "Sign with DomainKeys selector..." action to content filter.

  o Added DisableWebAdminAccess=Yes/No (Default: No) key to WorldClient's
    domains.ini file.
    
  o In WorldClient more feedback is presented to the user if they cannot
    create or edit an item because of insufficient access rights.

  o Contacts folders are now listed in various places with an abbreviated
    format to allow for sub folders of a greater depth.  In addition the
    folder's owner is always displayed to help clarify the source of the
    contacts.

  o All Windows CE devices should get the PocketPC theme for WorldClient now.

  o Added scrollbars to Tarpit|Advanced.

  o The IMAP server now supports the LOGIN authentication mechanism.

  o Various SPF related options are now disabled by default.  You should go
    into Security|SPF and make sure the settings there are what you want.
  
  o Significant improvements to calendar performance in WorldClient for users
    who are not using the Lookout theme.

  o API function MD_VerifyUserInfo now converts domain to all lower case.

  o New lists default to disallow EXPN commands

  o Added domain functions to MDUserCOM (doc not updated yet)

  o MDUserCOM.dll version will now be the same as the current MDaemon

  o The default score applied to messages which pass SPF processing was
    changed from -2.5 to 0.

  o A new switch was added to the logging options which governs whether the
    'all' log file will be created.

  o MDStats now includes the MDAV message quarantine directory in its list
    of queues.

  o By default, a new installation will store queues under a \Queues\ root
    directory.  If you would like to move your queues to this more organ-
    ized structure see the new Restore tab in the Queues GUI.

  o The Statistics log now contains MPOP and DPOP line entries for each
    message collected via MPOP or DPOP.

  o Cleaned up inbound SMTP logging to make it look more consistent.

  o The installer now backs up the SpamAssassin 'rules' directory to the
    \Backup\ folder and the layout of how files are stored there has changed
    slightly.  The format is now \Backup\%VERSION%\<sub dir>.

  o The installer now includes MDMigrator which is a tool to move from MS
    Exchange to MDaemon.  MDMigrator.txt contains instructions.  Previously
    this file was downloaded separately from our web site.

  o When spooling all mail to an ISP or upstream host any SMTP delivery
    error (temp 4xx or permanent 5xx) will return the message to the sender.

  o MDaemon no longer references or uses the MDAEMON_SPAM_BLOCKER SA rule.
    The rule is now called MDAEMON_DNSBL.  

  o Added IP being checked to SPF log info.

  o Added WC support for "x-uuencode" Content-Transfer-Encoding

  o MDaemon now creates SSL certificates with an exportable private key

  o Minor verbiage changes to Account Editor's Options tab.

  o Removed HOSTS file reference from SMTP log and NDR.

  o MDaemon now supports the processing of multiple A records in response
    to PTR lookups.

  o NDR's where changed to appear from MDaemon@<machine name> rather
    than MDaemon@<domain of sender>.

  o The order of the various Received and status headers was changed to
    bring MDaemon more inline with examples in the various RFC's.  

  o Old dnsBL sites that are no longer functioning were removed from the
    SpamBlck.dat file.
