Can't remove or clear mail from mail queue in panel

[Dean_Collins]

Version 12.0.18. Using QMail.

If I attempt to remove even a small message from the mail queue, using the panel interface, the screen grays slightly but nothing happens. If I refresh the screen after several minutes, I'll sometimes get the following message:

"This operation is taking too long. Check the results in a few minutes."

Switching to Postfix eliminated the problem. But with Postfix, all of my Mailman lists (scores of them) broke, so I had to switch back -- and the problem reappeared.

Any related error messages from mail log?

I'm not sure what I'd look for. The mail doesn't get stuck in the queue. It moves in and out in what appears to be a normal rate. No trouble at all sending and receiving mail.

Additional info if applicable: This wasn't an upgrade. It was a recent migration from a server with 10.4 to a new server with 12.0. Everything else is working.

Sigh.

I had the exact same issue myself, with qmail on Plesk 12.x and CentOS 7.

Turns out /usr/local/psa/admin/sbin/mailqueuemng used the old way of starting and stopping qmail, by using the /etc/init.d/qmail script. However, this script does not exist anymore because of systemd.

So I made a backup of the mailqueuemng script and replaced this code block (lines 34-36)

# While this is if you have a Debian GNU/Linux with its qmail package
my ($stopqmail)  = '/etc/init.d/qmail stop > /dev/null';
my ($startqmail) = '/etc/init.d/qmail start > /dev/null';

with

# While this is if you have a Debian GNU/Linux with its qmail package
#my ($stopqmail)  = '/etc/init.d/qmail stop > /dev/null';
#my ($startqmail) = '/etc/init.d/qmail start > /dev/null';

# If you can control qmail through service, use this
my ($stopqmail)  = '/sbin/service qmail stop > /dev/null';
my ($startqmail) = '/sbin/service qmail start > /dev/null';

(I left the old code in, just commented it out.)

Pretty sloppy of the Plesk developers to not have caught this during testing. Even sloppier that /sbin/service was not used, even though it's been around for about 8 years and has been the recommended way of starting and stopping services ever since.

Today I updated Qmail through Plesk and sure enough, the bug still exists in the script. I'll see if I can contact the company.
