我设置了 Postfix，使用 Dovecot 运行，支持 SASL，在 Postgresql 数据库中使用虚拟邮箱，Amavis Clamav 和 Spamassassin 都协同工作
工作 = 我可以向内部和外部 (google) 帐户发送和接收电子邮件。收到电子邮件后，它会存储在虚拟邮箱中 -- /mwdmail/mbox/example.com/[电子邮件保护]/
不工作- 我无法从外部网络远程登录到端口 25 - 当我成功本地远程登录到端口 25 时，我收到“连接被拒绝”的提示，也没有看到 AUTH LOGIN
如何使 Dovecot SASL 工作？
以下是我的设置：
- 我的路由器和 ufw 防火墙在端口 80、433、25、110、143、465、587、993 和 995 上打开
- Postfix 版本是 2.11.0

更新
Anders Klaer——感谢您的更新和提示！
在 master.cf 中添加 smtpd 行并重新加载 postfix但是，当我从同一网络上的另一台机器通过 telnet 端口 25 连接到本地主机和我的内部 IP 地址时，AUTH LOGIN（SASL“已启用”）代码不存在。

答案1
据我所知，您的 master.cf 缺少此行。将其放入您的配置中并执行sudo service postfix reload
# /etc/postfix/master.cf
# Listen on port 25.
smtpd pass - - - - - smtpd
要仅在建立 TLS 加密会话后提供 SASL 身份验证，请指定以下内容：
/etc/postfix/main.cf:
smtpd_tls_auth_only = yes
从您的main.cf设置smtpd_tls_auth_only为yes。将其更新为no并重新加载 Postfix 应该会为您提供 AUTH。
