Image only spam

[Jack Gostl]

I'm running SpamAssassin version 3.0.3   running on Perl version 5.8.2 under 
AIX 5.3. Starting a few months ago, I have been absolutely inundated with 
"image only spam".  I've gone from catching 99% of the spam with almost no 
false positives to less than 85%. I asked about this awhile ago, and tried 
to upgrade to SpamAssassin version 3.1.1   running on Perl version 5.8.0, 
and didn't see much improvement, so I left the prod machine alone.

I'm sure I'm not the only one with this problem. Has anyone had any success 
with it?

Thanks...

Jack
