Mail Server not receiving nor sending emails.

aaP_busso

Ubuntu 20.04
AAPanel 6.8.13
MailServer 4,3

After upgrading MailServer from version 4.2 to 4.3 , no more email are received or sent.
Mail Log doesn't show any error.
Users can login to their account without any problem but no new mail arrive.
Tried to send email through MailServer Setting popup: it says "Message sent succesfully" but no email reached the recipient ( f.ex. @gmail.com)
Tried to restart Postfix, Dovecot and Opendkim, tried to restart AAPanel and to reboot server, but no success.

Could you help me in fixing this matter?

Many Thanks
Nick

Also tried to uninstall and reinstall MailServer (Aapanel downloaded 4.3 again).
MailServer asked me to install Redis (that wasn't installed) and set a password for it)... I did everything.
Now MailServer is installed: Dovecot and Postfix are running, RSpamD isn't running and if I try to Start it, it suddenly stops

Outgoing mails are now OK (even if now they are marked as SPAM by Google... before upgrading to MailServer 4.3 everything was ok).....No mails are received (even mails sent by the same domain).

Any tip will be appreciated....

please show me the rspamd status
systemctl status rspamd

Into the spam mailbox because dkim cannot be obtained (rspamd cannot be started)

If your problem needs to be solved urgently,
please send the login information of the panel to jose@aapanel.com, I will check it for you after receiving it
