Resolved Emails are all in the queue

[zepelin57]

Hello,

I no longer understand anything, incoming and outgoing emails are all in the queue, marked deferred.
Yet it has been working well for months.

In mailog I have:

Nov 5 22:52:42 xxxxxxxxx postfix/smtp[25767]: 66E04180E10: to=<[email protected]>, relay=127.0.0.1[127.0.0.1]:10024, delay=0.38, delays=0.35/0/0.01/0.02, dsn=4.3.2, status=deferred (host 127.0.0.1[127.0.0.1] said: 421 4.3.2 Service shutting down, closing channel (in reply to RCPT TO command))

Thanks for your help

Looks like Plesk Email Security not installed on the server, however, amavis is present. Or Plesk Email Security is in 'Disabled' status. In this case, just remove amavis package:

# rpm -e amavis
