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]
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。）
[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/".

# 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？？
