Dovecot/RainLoop/CyperPanel/GCP VM 邮件问题

问题描述

我见过很多类似的问题，但好几天都没有找到解决方案。 我在 GCP Ubuntu VM 上运行 CyperPanel。 登录 RainLoop 时，我收到错误“授权失败”。

这是我要跑的东西

systemctl status dovecot

运行

有什么建议可以看吗？ 我不会发布我尝试过但没有用的解决方案，我愿意再次发布结果。 提前致谢！

//编辑 尝试的解决方案：https://forums.cyberpanel.net/discussion/4807/cant-login-to-rainloop

I installed Cyberpanel on Ubuntu 20.4 minimal on GCP but the problem remained.

Followed the next steps found on another discussion to solve:

apt remove dovecot-core dovecot-mysql dovecot-pop3d dovecot-imapd
sed -e '/deb/ s/^#*/#/' -i /etc/apt/sources.list.d/dovecot.list
apt clean all
apt install dovecot-core dovecot-mysql dovecot-pop3d dovecot-imapd
apt-get install -y libmysqlclient-dev

Then check devecot status with:

systemctl status dovecot -l

Then you go to YourIP:8090/manageSSL/sslForMailServer and install a SSL certificate for your Domain.

Then it will work

现在出现新错误：

root@cyberpanel-2-vm:/home/admin_# journalctl -f | grep dovecot
Mar 03 17:00:33 cyberpanel-2-vm dovecot[824]: imap-login: Disconnected (auth failed,1 attempts in 2 secs): user=<[e-mail]>,method=PLAIN,TLS,session=<J7XgyaS8VJZ/AAAB>
