我的postfix + dovecot安装有问题。 自从七月份以来，我的所有人都不再工作了。 我几天前才意识到这个问题，因为我的一个朋友明确地向不存在的地址发送了一封邮件，而且没有到达。 于是我挖掘了几个日志，发现这个全部看起来不再起作用。
看着邮件存储目录，我看到Dovecot在@之前为每个“用户”创build了新的邮箱，而不是将其发送到我的邮箱。 这些邮箱中最老的是从七月份开始，所以我觉得那里出了问题。 一年以来，我还没有改变我的后缀/ dovecotconfiguration。
编辑：最后一句话是不正确的。 今年早些时候，我从服务器上删除了ClamAV。 也许我搞砸了？
但是，我总是在到达时安装更新。 该服务器正在运行Debian Squeeze。
这是我的后缀configuration：

我的MySQL数据库的转发看起来像这样：
mysql> describe forwardings; +-------------+-------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +-------------+-------------+------+-----+---------+-------+ | source | varchar(80) | NO | PRI | NULL | | | destination | text | NO | | NULL | | +-------------+-------------+------+-----+---------+-------+ 2 rows in set (0.00 sec) mysql> select * from forwardings; +--------------+-----------------------+ | source | destination | +--------------+-----------------------+ | @mydomain.de | [email protected] | +--------------+-----------------------+
Dovecot日志文件显示postfix不能parsing正确的目的地：
2013-09-05 16:27:20 deliver([email protected]): Info: msgid=<[email protected]>: saved mail to INBOX
logging来自postfix的MySQL查询：
130905 16:09:34 68 Query SELECT domain AS virtual FROM domains WHERE domain='other.com' 68 Query SELECT domain AS virtual FROM domains WHERE domain='mydomain.de' 69 Query SELECT destination FROM forwardings WHERE source='[email protected]' 70 Query SELECT email FROM users WHERE email='[email protected]' 69 Query SELECT destination FROM forwardings WHERE source='@mydomain.de'
最后一行表示postfix尝试parsing不存在的地址。 手动执行查询：
mysql> SELECT destination FROM forwardings WHERE source='@mydomain.de'; +-----------------------+ | destination | +-----------------------+ | [email protected] | +-----------------------+ 1 row in set (0.00 sec)
所以一切似乎都到位，应该工作。 但事实并非如此。 有没有人有一个想法可能会导致这种行为？

问候，塞巴斯蒂安
在你的main.cf你有receive_override_options = no_address_mappings 。 这使禁用所有。 删除此行以再次启用它。
你可能在postfix实例的configuration中有不同的receive_override_options在之前启用了catch-all的clamav内容filter之后。
