- CentOS Linux 7.9.2009
- Plesk version and microupdate number
- Obsidian v18.0.57
Recently I restarted VPS server hosted at Hetzner. First i could not access Plesk admin and Plesk update page, and I had to manually open permanent ports in CentOS with SSH.
I didn't have this problem before after server restart, the only difference is that I turned off Plesk firewall and I configured Hetzner firewall.
The problem I had now is that I can not receive emails anymore, I can still send emails, but server is not receiving email on any domain.
The strange thing is that everything was working perfectly before server restart.
I also manually added all the necessary ports in CentOS firewall.
Also switched from Postfix to QMail but no change in behavior, and tried to turn off "Enable SMTP service on port 587 on all IP addresses" function. I also tried to disable suexec as I read somewhere that in some cases this can be a problem.
Do you have any ideas? I did read other similar threads on the forum, and I already spent sometime trying to fix this.
