I'm using cyberpanel and webmail service is RainLoop but today I noticed that I can not send or receive mail, when I send email, it give me an error on send button
Can't send message
Then I checked email logs:

I also checked systemctl status postfix, and result is:

Hint: Some lines were ellipsized, use -l to show in full.
Any idea what is the problem? and how can I fix it?
