Please don't use C/R.  It's one of those solutions that's extremely
effective if 0.01% of the Internet uses it, but will destroy e-mail if
lots of people use it.

Is one porn spam a month really that bad?  (I use a text-based mail reader,
so perhaps I'm spared obnoxious images, but really... a few bad words
a month isn't the end of the world.)

I do have my own anti-porn rules, but I hesitate to post them because they'll
probably trigger alarms on all your anti-spam systems. :-)
