谁能告诉我什么是后缀告诉我这个错误？

我应该认为这是同样的问题吗？ 后缀/ dovecot / mysql不发送/获取电子邮件
我也收到这个dovecot错误：auth-worker（1560）：错误：mysql（本地主机）：连接失败数据库（postfix_db）：访问被拒绝用户'postfix'@'localhost'（使用密码：YES）现在刚才在telnet上testingimap的时候才意识到，并试图用一个已经创build的用户login和不用域，可能是这个相关吗？
postconf -M的输出会告诉你master.cf的有效条目。 基于此，看起来像你有遗漏的代理地图条目。 把这一行放在master.cf
proxymap unix - - n - - proxymap
因为您已经在main.cf中设置了启用代理选项，所以postfix需要Proxymap服务 。 这些configuration是virtual_alias_maps ， virtual_mailbox_domains和virtual_mailbox_maps 。
出于一个奇怪的原因@masegaloeh的答案不与我一起工作，而是当我使用这个，试图解决另一个错误，它修复。 所以不会说这是正确的答案，但我无论如何都不愿意帮助任何人解决类似的问题。
我只是在我的/etc/postfix/master.cf文件中添加这一行，因为我有这样的smtpd错误：“子系统公共/清理：连接被拒绝”和voilá，两个错误都没有了。
cleanup unix n - n - 0 cleanup
我有相同的“ subsystem public/cleanup: Connection refused ”的问题，但是当我看着/etc/postfix/master.cf文件，提到的行已经在那里。 所以在我的情况下解决scheme是简单地重新启动后缀：
service postfix restart
在那之后，我收到了之前没有寄出的所有电子邮件，而且这很多。
