Postfix emails stuck in mail queue

[Justin Clarke]

Hi,

I have a bunch of Postfix emails stuck in the mail queue, even when I run:

postqueue -f

Nothing happens.

Any ideas?

Thanks.

Even if I do a:

postqueue -p

It says:

Mail queue is empty.

But in Plesk Panel Mail Server Settings > Mail Queue it shows about 6 items in there!

Swithed MTA to QMail now, so this doesn't apply.
