邮件服务器发送/接收问题

邮件服务器发送/接收问题

我已经使用 Postfix、Dovecot 作为我的 SASL 和 Rainloop 作为我的 WebClient 设置了一个邮件服务器。我正在使用MySQL(询问后我的最后一个问题)对于我的用户帐户和密码,并且它工作正常,但我面临两个问题。 [第二个问题已经解决了]

  1. 我无法接收电子邮件! (我只需要员工通过电子邮件联系,他们目前无法收到任何电子邮件,当我从一名员工向另一名员工发送电子邮件时,我找不到任何日志文件显示失败的迹象,我真的不知道什么可能是无法接收的问题。)

  2. [已解决] 用户可以通过 ThunderBird 登录,因为它会要求确认 SMTP 和 IMAP 的证书。即当我登录时,我应该接受证书,并且第一次发送邮件时,我应该接受另一个证书,然后它就会起作用。但 Outlook 无法登录,因为它只为 IMAP 请求一次证书。

这是我的配置文件:

我有 3 个数据库表:virtual_domains、virtual_users、virtual_aliases。 Postfix知道所有这些,并且已经通过postmap命令证明了这一点,并且配置在mysql-virtual-mailbox-domains.cf,mysql-virtual-mailbox-maps.cf,mysql-virtual-email2email.cf,mysql-中设置虚拟别名映射.cf。

  # useful when converting from another server with different namespaces which

  # hidden namespaces with prefixes "~/mail/", "~%u/mail/" and "mail/".
  #hidden = no

  # namespace visible for clients that don't support NAMESPACE extension.

  # Namespace handles its own subscriptions. If set to "no", the parent
  # namespace handles them (empty prefix should always have this as "yes")

我愿意接受任何建议,即使是从头开始。但请准确并详细解释,我不是设置邮件服务器的专家。提前致谢。

如果还需要任何其他信息,请告诉我,我将使用所需的配置文件更新问题。

更新:

伙计们,我不知道为什么我无法收到电子邮件,而一切似乎都是正确的,有人可以帮忙吗?任何想法??
