Dovecot：断开连接，连接关闭，身份验证失败

我在 Ubuntu Server 22.04（VMware Workstation 16 虚拟机）上安装了 Postfix+Dovecot。然后我部署了 Ubuntu 22.04 Desktop 并开始在 Geary 中创建新邮箱。但它显示“未创建帐户：请检查您的发送服务器详细信息”。我可以在 中看到一些有趣的条目/var/log/mail.log。

Jan 19 16:40:17 mailserver dovecot: imap-login: Disconnected: Connection closed (auth failed, 1 attempts in 4 secs): user=<obfuscated>, method=PLAIN, rip=192.168.0.220, lip=192.168.0.212, session=<JX+MEp7ymNTAqADc>

服务器名称为mailserver.example.com。用户邮件：[电子邮件保护] SSL/TLS：没有。

以下是 的 nmap 结果mailserver。

PORT    STATE  SERVICE
22/tcp  open   ssh
25/tcp  open   smtp
80/tcp  open   http
110/tcp closed pop3
143/tcp open   imap
443/tcp closed https
465/tcp closed smtps
587/tcp open   submission
993/tcp closed imaps
995/tcp closed pop3s

我想我应该添加有关用户的信息，但我不知道在哪个文件中。

答案1

日志中有一个错误：

mailserver postfix/proxymap[75657]: error: open /etc/postfix/mysql_virtual_domains_maps.cf: No such file or directory

所以我创建了该文件并且它已开始通过 Roundcube 发送消息！
