Topic: Emails send and receive stop working after midnight

I am using IredAdmin Pro 1.6.8 MARIADB edition and deployed with easy installer, My OS is ubuntu 22.04. I am using this server from many months and it was working ok, all in sudden we started facing emails sending and receiving issue. All services are seems up but noting happening then i do a server reboot then all start working. My OS is fully updated and also IreAdmin Pro with latest ver.

Re: Emails send and receive stop working after midnight

- Any related error in /var/log/syslog and /var/log/maillog?
- How much memory does this server have?
- Are clamav-daemon and amavis services running?

I restarted my iredmail pro server and even after that it was not delivering emails.. then i saw after restart postfix was not working i restarted the postfix then gave command postqueue -f then all good.

Please help me on this to resolve asap.
