目前我正在开发自己的邮件服务器，但目前我无法正确启动 SMTP。
我使用 Dovecot 和 postfix。
当我尝试将我的服务器添加到我的邮件客户端时，它告诉我：
传出：SMTP（我的服务器地址）：587，无 SSL，身份验证：普通密码
我不知道为什么我会得到这个结果，因为我以为我已经设置好了一切。
我到今天为止还没有使用过 Postfix，所以我不知道缺少了什么或者出了什么问题。
系统：全新 Debian 10 x64，
安装了 postfix、dovecot-core、dovecot-imapd 和 dovecot-pop3d。
这是我的 postfix main.cf：https://pastebin.com/S17jWDQd
这是我的 postfix master.cf：https://pastebin.com/W0nynZG6
这是我的 dovecot.conf：https://pastebin.com/tMD90Znn
这些内容大部分都是从 iRedMail 安装中复制而来的，所以我认为我在复制和修改以供自己使用时遗漏了一些东西。
这是我的邮件日志：

答案1
修复此错误最明显的方法是安装postfix-pcre提供该功能的软件包。然后 Mozilla 自动检测应该能够与 Postfix 通信。
