There are no mailboxes on the system I'm trying to do this on. It's a 
relay server and I rather not get another server in the mix. I want to 
see if I can accomplish it on the same system. Could I somehow query the 
database and output the contents into a file and feed that to 
spamassassin? Has anyone tried anything like this before. I can't be the 
only one?
