one thing that spamassassin has that i really like is the SURBL checking 
mechanism.  it scans an email for any URL-looking strings and then 
checks the domains in those URLs against a central database of known 
spammer URLs.  so even in the case of "message with nothing but a jpeg 
URL" you'd still get a spam warning if the SURBL database has seen that 
particular item.  checking spamassassin on my local server i see that 
90% of my spams trip either the Bayes filter and the SURBL check, making 
them the most effective spam fighting tools in my arsenal.

see http://www.surbl.org/ for more info.
