我已经按照教程设置了一个测试服务器https://arstechnica.com/information-technology/2014/02/how-to-run-your-own-e-mail-server-with-your-own-domain-part-1/
问题在于尝试使用 Thunderbird（或任何客户端）登录。Thunderbird 抱怨它找不到我的电子邮件帐户的设置。这是启用调试的 dovecot 日志。
Mar 9 11:44:30 mydomain dovecot: auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth

我的证书之前出现了问题（我是自行签名的） - 但在我添加了例外之后，Thunderbird 很高兴地接受了它。
我能够通过 telnet 远程访问我的邮件服务器。
openssl s_client -connect mydomain.com:143 -starttls imap
CONNECTED(00000003)
从这里我可以登录我的帐户并查看收件箱。
我还可以连接到993端口并登录。
openssl s_client -showcerts -connect mail.mydomain.com:993
但 Thunderbird 一直告诉我“无法找到您的服务器设置”。从 gmail 发送到服务器的消息也失败了。
建议？
