Input Problem with emails after updating to Plesk Obsidian Version 18.0.40 Update 1

[mw004]

Hi,

I have a problem with emails after updating to Plesk Obsidian Version 18.0.40 Update #1.
Some emails stay in mail queue with days . There are no errors in the mail logs.
Please help where to look for the problem?

Thanks,

Please type

mailq

in your terminal - there will be the reason for the long duration. You can paste the output here if you want, but don't forget to censor the ip addresses and mail addresses.

"Messages in queue: 0 not preprocessed, 4190 local, 0 remote, 4190 total"

And they are growing.

But what does this help me with?
No changes have been made to the server other than the plesk panel update.
There are no errors in the logs.

Is your mailserver (qmail?) running? It looks like it stopped for some reason.

Dovecot IMAP and POP3 server. And everything works, but I don't receive emails.

IMAP and POP3 are not for delivery. Please look for QMail or Postfix

Qmail.
But I have a problem with incoming emails. I get the same with a delay.

But you said you have an issue with Mails in the queue. So that means they are not delivered. No matter if incoming or outgoing.
And what does the log say?
