在我的Linode上，我按照这个文档来设置邮件服务器。
现在我可以发送电子邮件到任何域名，但不能从其他域接收！
我的意思是[email protected]可以从[email protected]收到邮件，但不能收到xxx @ gmail / yahoo / … com的任何邮件。 我也检查了我的vmail（Maildir），其他域的邮件不在那里。
我收到来自gmail的邮件状态通知（延迟） （约24小时后）：
Delivery to the following recipient has been delayed: [email protected] Message will be retried for 2 more day(s) Technical details of temporary failure: The recipient server did not accept our requests to connect. Learn more at http://mail.google.com/support/bin/answer.py?answer=7720 [mail.mydomain.com. (10): Connection refused] 这是我的设置：
我有一个MXlogging：
mail.mydomain.com
和A / AAAAlogging ：
mail (with same ip as my server)
我的/ etc / hosts

我的/ etc / default / saslauthd
START=yes DESC="SASL Authentication Daemon" NAME="saslauthd" MECHANISMS="pam" MECH_OPTIONS="" THREADS=5 OPTIONS="-c -m /var/spool/postfix/var/run/saslauthd -r"
我的/ etc /别名

我的iptables规则：
（我使用2525而不是25端口，它在我的机器和isp打开，我可以远程login）
pkts bytes target prot opt in out source destination 130 7820 ACCEPT tcp -- any any anywhere anywhere tcp dpt:smtp 0 0 ACCEPT udp -- any any anywhere anywhere udp dpt:25 388 33099 ACCEPT tcp -- any any anywhere anywhere tcp dpt:2525 0 0 ACCEPT udp -- any any anywhere anywhere udp dpt:2525 0 0 ACCEPT udp -- any any anywhere anywhere udp dpt:100 0 0 ACCEPT udp -- any any anywhere anywhere udp dpt:pop3 65 3538 ACCEPT tcp -- any any anywhere anywhere tcp dpt:pop3 0 0 ACCEPT tcp -- any any anywhere anywhere tcp dpt:26 0 0 ACCEPT udp -- any any anywhere anywhere udp dpt:26 0 0 ACCEPT udp -- any any anywhere anywhere udp dpt:pop3s 2355 184K ACCEPT tcp -- any any anywhere anywhere tcp dpt:pop3s
日志
当我收到其他域邮件时，没有任何东西添加到我的/ var / log / mail.log中 ，但是当我尝试通过邮件客户端收到邮件时， 似乎没有问题 。
Apr 14 07:53:51 hostname dovecot: pop3-login: Login: user=<[email protected]>, method=PLAIN, rip=94.182.127.182, lip=178.79.152.29, TLS Apr 14 07:53:52 hostname dovecot: POP3([email protected]): Disconnected: Logged out top=0/0, retr=0/0, del=0/7, size=6546
/ home / vmail / dovecot-deliver.log没有任何反应，当我从其他域收到邮件，但在相同的域名电子邮件似乎正常：
2011-04-14 05:42:53 deliver([email protected]): Info: msgid=<[email protected]>: saved mail to INBOX
我通过VMail，Mutt，Apple Mail和Thunderbird检查邮件，这是我在邮件客户端上的设置：
帐户types： pop3
传入邮件服务器： mail.mydomain.com
用户名： [email protected]
密码： XXXXX
对外邮件服务器：
服务器名称： mail.mydomain.com
港口： 2525
使用SSL
自动分配：密码
用户名： [email protected]
密码： XXXXX
由于在/var/mail/mail.log中绝对没有logging任何东西，并且你的链接显示零stream量进入tcp / 25，我相信你的ISP阻止在tcp / 25上的传入stream量。 这对于家庭用户来说是正常的做法。 除非你有一个商务舱的连接，否则ISP不允许他们的用户stream量指定为tcp / 25。
你需要一些类似DynDNS'mailhop的外部服务。 您将DynDNS设置为您的MX，并将其邮件转发到您的服务器上打开的目标端口，如2525。
编辑： 要清楚 ; 真正的互联网电子邮件只能通过端口tcp / 25。 你不能像2525那样打开一个端口，并期望它工作。
由于我的ISP也阻塞端口25，我添加了另一个端口（2525）到/etc/postfix/main.cf。 但是，我犯了一个错误，将smtp端口注释掉，导致从外部接收邮件失败。
# Does not work #smtp inet n - - - - smtpd 2525 inet n - - - - smtpd
要接收来自其他服务器的邮件，并绕过ISP的端口限制，只需打开端口25（smtp）和另一个端口即可。
# Works smtp inet n - - - - smtpd 2525 inet n - - - - smtpd
