Thanks so much,   What a great product Mimedefang.

FYI, being a educational institution we get Redhat for like $25.

Here's some free advice:  On RHEL3, type "ulimit -s": 
 
$ ulimit -s 
10240 
 
So each thread wants 10MB of stack space.  That can chew up your RAM
pretty 
quickly.  I recommend editing the MIMEDefang startup script and putting:

 
ulimit -s 2048 
 
just before mimedefang (not the multiplexor!) is invoked. 
 
Right now, the sample red hat script does it only if you have more than 
100 slaves, but it should really do it unconditionally.
