我虽为网管却自认很惭愧。请大师、高人为我指点迷津……置顶的帖子亦不能解决我的问题 
 
我虽为网管却自认很惭愧。请大师、高人为我指点迷津…… 
 
再问“如何解决不能往163、sina发邮件问题” 
 
一、环境 
 
telnet mail.mydomain.com 
Red Hat Linux release 7.3 (Valhalla) 
Kernel 2.4.18-3 on an i686 
login: 
 
telnet mail.mydomain.com 25 
220 mail.mydomain.com ESMTP Sendmail 8.11.6/8.11.6; Tue, 1 Feb 2005 19:43:55 +0800 
 
二、现在的配置 
 
$ more /etc/hosts 
# Do not remove the following line, or various programs 
# that require network functionality will fail. 
127.0.0.1 localhost.localdomain localhost 
61.135.152.85 mail.mydomain.com mail mail.mydomain.com ns 
$ hostname --fqdn 
mail.mydomain.com 
 
$ more /var/named/s/mydomain.com.hosts 
@ IN SOA ns.mydomain.com. root.ns.mydomain.com. ( 2004940039 1800 600 100800 1200 ) IN NS ns IN MX 10 mail.mydomain.com. 
localhost IN A 127.0.0.1 
ns IN A 61.135.152.85 
mail IN A 61.135.152.85 
 
$ more /var/named/s/61.135.152.rev 
@ IN SOA ns.mydomain.com. root.ns.mydomain.com. ( 2003063814 10800 3600 604800 28800 ) IN NS ns.mydomain.com. 
85 IN PTR ns.mydomain.com. 
85 IN PTR mail.mydomain.com. 
 
$ more /etc/mail/sendmail.mc 
divert(-1) 
dnl This is the sendmail macro config file. If you make changes to this file, 
dnl you need the sendmail-cf rpm installed and then have to generate a 
dnl new /etc/sendmail.cf by running the following command:

四、问题 
依照网络上众多不能往sina、163发信的解决方案的帖子，根据我的配置已经排除了mx记录、fqdn、ip反向解析的可能，可是为什么仍然不能发信？并且我得到是441而非553错误…… 
另已经查询了反垃圾邮件联盟，域名、ip均不在其列表。 
我怀疑是sendmail.mc的问题，可是不知错误在哪应该修正何处呀？我身为网管却自认很惭愧。请大师、高人为我指点迷津……

看Sendmail.mc中的"dnl DAEMON_OPTIONS(`Port=smtp,Addr=0.0.0.0, Name=MTA')",把红色部分改为你的主机IP并注释掉(删除dnl)试试.
