Hi
After new installtion of cyberpanel 5days ago , the email cannot sent but reciving…
According to this command
journalctl -f | grep postfix (For email delivery issues)
journalctl -f | grep dovecot (For issues related to Rainloop Webmail)
I got many errors and after 30min I canceld the opreation
Now I’m upgrading the cyberpanel but I don’t think to fix that
after upgrade the problem persist

What is the problem?
