Heh, funny, three different answers in this thread and AFAICT they 
are all correct to some extent.

I think the "passdb { deny=yes }" is the best answer. I implemented 
this in SQL using a tri-state "active" column. Standard "active=1" 
means the MTA accepts mail and the user can login. "active=0" will 
disable both. The third state, "active=-1" has the MTA continuing to 
accept mail, but triggers my deny=yes passdb.
