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……
