IF you know what relay or relays you want to watch, this might help a 
bit. We watch webserver relays on mailscanner boxes with cheap little 
shell scripts that run from cron frequently like this:

cd /var/log/
for i in `tail -1000 maillog | \
grep "relay=$RELAY" | \
grep -v "STARTTLS" | \
awk '{print $6}'`; \
do grep $i maillog | \
grep "is spam\|black.uribl.com\|surbl.org"; \

It mostly reports on form & forum php-spam pushing pills with links to 
uribl or surbl listed sites (milter-link). Once in a while it catches a 
false positive or an exploited script, which looks quite similar to a 
compromised account.. thousands of messages to hotmail and aol 
addresses, lots of spooled mail to delete, etc..
