我有一个 postfix 邮件服务器，用于将发往我的域名的所有电子邮件转发*@example.com到单个虚拟邮箱：[email protected]。
我通过以下配置做到了这一点：
/etc/postfix/main.cf
virtual_alias_maps = mysql:/etc/postfix/mysql-virtual-alias-maps.cf regexp:/etc/postfix/aliases-regexp
/etc/postfix/aliases-regexp
（应该转发任何内容不是已经去[email protected])
!/me@example\.com/ [email protected]
接收邮件正常：

请注意以下这一行：
postfix/pipe[5858]: E7D49E27: to=<[email protected]>, orig_to=<[email protected]>, relay=spamassassin, delay=0.54, delays=0.13/0.01/0/0.4, dsn=2.0.0, status=sent (delivered via spamassassin service)
显示该消息原本是发给 的，[email protected]但已送达[email protected]。这很好。不幸的是，这种情况也会发生在发送过程中。这会导致发送的消息被退回给我。

这是发送邮件时的完整日志：

结果是我的消息似乎没有发送，甚至没有收到错误回复。
答案1
在 Postfix 中为域名创建 catch-all 有很多选项，您的选项比较复杂。通常的方法是使用virtual_alias_maps = hash:/etc/postfix/virtual。使用 时@example.com me请记住。postmap /etc/postfix/virtualhash:
答案2
我通过改为解决了这个问题/etc/postfix/aliases-regexp：
if /(.*)@example.com/
!/me@example\.com/ [email protected]
endif
if 语句首先检查邮件是否发往该域，不包括外发邮件。
