Dovecot-core 启动失败

我正在尝试遵循本教程：

https://www.digitalocean.com/community/tutorials/how-to-configure-a-mail-server-using-postfix-dovecot-mysql-and-spamassassin

我相信在我之前有人尝试过在这个盒子上设置这一切，但中途失败了。我被困在第一个命令上：

sudo apt-get install postfix postfix-mysql dovecot-core dovecot-imapd dovecot-lmtpd dovecot-mysql

其结果是：

似乎 dovecot-core 没有正确启动...因此我运行：

systemctl status dovecot.service
journalctl -xe

结果如下：

● dovecot.service - LSB: Dovecot init script

和

Jul 15 13:43:47 postfix[24814]: error: to submit mail, use the Postfix sendmail command
Jul 15 13:43:47 postfix[24814]: fatal: the postfix command is reserved for the superuser

我现在陷入困境，不知道下一步该怎么做。任何建议都将不胜感激……

编辑：我很乐意重新开始。如果有办法彻底删除这些安装并重新开始，我很乐意这样做，如果这比修复这个问题更容易。

答案1

只需运行 sudo apt-get purge dovecot-core 即可修复
