    I have some users complaining that certain emails are taking many hours to be received or are not received at all.
    This has only been an issue since upgrading to 9.5. I'm using qmail.

    I disabled greylisting on the server and it's still a problem.
    It's very hard to recreate as emails sent by me come thru straight away.

    Some senders have received this bounce message:

    "451 qq trouble in home directory (*4.3.0. deferred 451 qq. Message could not be delivered for 3 hours, message will be deleted from queue."

    I've installed all the latest updates and performed:
    /usr/local/psa/admin/sbin/mchk --with-spam

    But this issue still persists, please help.

    I can assume that problem related to impossibility of resolving some domain names. Do you have something like

    failure: Sorry,_I_couldn't_find_any_host_named_domain.com._(#5.1.2)/

    related to these emails in Plesk maillog /usr/local/psa/var/log/maillog? Check that these domains are resolvable from your Plesk server.

    Is amazon.com resolvable from your server?
    Check it with 'host' command at least.

    Seems there is problem with your DNS servers described in /etc/resolv.conf
    I have following:

    As you can see - it is without any errors.

    For three weeks now I have experienced the same problem . . . several clients hosted on my PLESK server say when they send emails more than half are never received by the intended recipient. I am running 10.1.1. A message sent to two addresses, one to an address hosted on my server will go through, the other addressed to 'an outside' email host will just disappear. Any solutions?
