We're trying to replace a Windows anti-spam on the mailbox servers 
with amavisd/sa/clam on the front-end mx.

We are running both now.  the backend mail scanner is still catching 
too many true spams.

We uploaded the backend spams to the mx and run them through spamc, 
with these results:

All of the above files are below the amavis max file limit to send to 
sa, so they should be scanned.

how do the the eml's with 5+ on just the body (not the sending IP) 
getting through amavis/sa?

our sa rulesets:

mx1# ll /usr/local/etc/mail/spamassassin/

Any suggestions for other rulesets?

thanks
