IMail 2006.21 Description:
Ipswitch 于2007年7月18日发布IMail Server 2006.21或是称为IMail Server　9.21，修正内容如下：
This update fixes a variety of issues.
Web Client - CuteEditor by CuteSoft Components, Inc., a new HTML editor has replaced FreeTextBox for composing messages.
New release of Premium Antispam (Mail-Filters): IMail Server 2006.21 also includes an update to the Premium Antispam (Mail-Filters) software. The latest version of the StarEngineService provides new options for configuring spam filtering of message header content. These options are available on the Premium Filter Settings page. (Click Services > Antispam.) Note: These settings apply to the selected domain.
Flag missing Subject: header as spam. Checks that the Subject Header field exists. If the Subject is missing, it will take the action specified in For email determined to be from a dirty IP section of the Premium Antispam Filter page.
Flag missing From: and To: headers as spam. Checks that both the From and To fields in the header exists. If either field is missing, it will take the action specified in the For email determined to be from a dirty IP section of the Premium Antispam Filter page.
These options help to filter emails sent as part of a campaign and to identify IP addresses used to send spam, also known as "dirty" IP addresses. When mail fails the header checks, IMail takes the action specified on the Premium Filter Settings page (click Antispam > Premium Filter).
Also on the Premium Filter Settings page, in the Update Engine Options section, the Enable Telemetry option was added.
