求助，postfix无法外发邮件。各位大大们，帮忙啊。。。

myorigin = /etc/mailname 可以这样写吗 ,我觉得是 olship.cn才对，就是你的邮箱后缀

smtpd_sasl_path = /var/run/dovecot/auth-client  这个地址在 /etc/dovecot.conf 里改

还有 /etc/dovecot.conf 里 加上这个
mechanisms = login plain digest-md5

加上mynetworks_style = host没有任何效果，以下是加上之后不做认证发送邮件，直接relay access denied。那位大侠能先告诉我一下，relay access denied是为什么？那条语句控制的？

mail:~# telnet localhost ...

mydomain=olship.cn
或者把 olship.cn 加到虚拟域里
要不然postfix 认为 olship.cn 不是你的域，当然 relay access denied,因为你是发向 gmail.com的
mail from:aaa@olship.cn

wzhihai

olship.cn已经在虚拟域里了。而且实际域名指向也是本服务器。另外在/etc/dovecot.conf里有mechanisms = login plain digest-md5，但telnet的时候还是报538 5.7.0 Encryption required for requested authentication mechanism

postmap -q "olship.cn"  mysql:/etc/postfix/mysql-virtual-mailbox-domains.cf 输出什么
dovecot.conf 去掉注释贴出来
还有 postconf -n 的结果

postmap -q "olship.cn"  mysql:/etc/postfix/mysql-virtual-mailbox-domains.cf
的结果显示1.

第一个问题是对方用户名不存在，还是设置了黑名单什么了吧。

如有需要的朋友，自己查看吧。目前收发域内邮件，和收发域外邮件都正常。

myhostname = mail.example.com
改成其它的就行了。
