some users getting copies of the same email over and over. ???

[motobrandt]

I have a few users that are receiving the same emails over and over. As in at least once a day and sometimes more then once. None of them seem to be legitimate emails. Mostly spam.

Is there a place where these could be bouncing around? I don't understand the frozen and retry stuff very well does that seem like a possible cause?

any suggestions will help.
