How are you flushing the mail from the queue? Webmin? Commandline?

Oh, just a quick note...this is normal when the remote server refuses an email or it doesn't exist.

Flushing actually isn't going to change this fact. (Deleting them will, though)

Those emails will eventually expire and NDRs will be delivered to the original senders .

Using Webmin to flush.
The domains exist.
They are my customers.
I also noticed that only big email (above 1mb) get stuck and only when the receiving end has exchange 2010.
Loaded a snapshot from 2 weeks ago with the same problem.
