[PLUG] Email Backing up

[R. Haack]

I'm having the following issue.  We got our email server up and running 
but some of our mail seems to be backed up at Clackamas ESD.  From what 
I can tell all of this email is junk, but our server should be pulling 
it down and then bouncing it.  I do get bounce/delayed deliver messages 
but still there seems to be stuff backed up down the pipe from us.  Any 
ideas what could be causing this problem?

Distro: Fedora Core 2
Using: Postfix with Cyrus

Thanks for all your help!!!!!!!!
