I've reinstalled my server with a clean Ubuntu SVR and CP 2.1.1.
Everything works well but emails.
Can't make the server send or receive on my domain (technovores.com).
DNS records seem OK
Firewall is OK
Ports are correctly forwarded
No SSL issue
Email I send to the serveur bounced (The recipient server did not accept our requests to connect.)
Rainloop was working but is telling now that the account is not allowed since I've done the chmod fix (chown -R cyberpanel:cyberpanel /usr/local/CyberCP/lib/python3.6/site-packages/tldextract/.suffix_cache) to give cyberpanel ownership to some files.
Any idea where I could investigate to troubleshoot this issue ?
I'm stuck, can't get email for my small company, It's a big issue for me :(
