我有一个 Postfix-Dovecot-Spamassassin-RoundCube 设置，其中有虚拟域和用户以 Maildir 样式接受邮件。但是，我最近所做的更改（虽然无法确定我做了什么）允许我从本地和外部来源（其他虚拟域或 Gmail）接收电子邮件，但只允许我向本地域发送电子邮件。当我尝试向 Gmail 发送电子邮件时，我看到/var/log/dovecot.info/：
Nov 10 14:19:52 auth: Info: passwd-file([email protected]): unknown user
运行dovecot -n | grep passwd返回结果为：
driver = passwd-file
我可以登录我的所有 RoundCube 电子邮件，并且如前所述，可以在本地发送电子邮件。我应该寻找（或调查）什么来进一步调查这个问题。
需要注意的是，当我通过以下命令发送电子邮件时
mail [email protected]
输入主题，正文然后发送即可ctrl+d成功发送电子邮件。

更新 1：
在我做出以下改变之后/etc/postfix/master.cf：
spamassassin unix - n n - - pipe
flags=DROhu user=vmail:vmail argv=/usr/bin/spamc -f -e
/usr/lib/dovecot/deliver -f ${sender} -d ${user}@${nexthop}
到：
spamassassin unix - n n - - pipe
flags=DROhu user=vmail:vmail argv=/usr/bin/spamc -f -e
/usr/sbin/sendmail -oi -f ${sender} ${recipient}
dovecot -n和的输出postconf -n为：

答案1
好吧，可能够简单了，但是对于我来说，我有以下内容/etc/postfix/master.cf：
spamassassin unix - n n - - pipe
flags=DROhu user=vmail:vmail argv=/usr/bin/spamc -f -e
/usr/lib/dovecot/deliver -f ${sender} -d ${user}@${nexthop}
我将其改为：
spamassassin unix - n n - - pipe
flags=DROhu user=vmail:vmail argv=/usr/bin/spamc -f -e
/usr/sbin/sendmail -oi -f ${sender} ${recipient}
并重新启动 postfix 并service postfix restart开始工作:-)
