Large spam

[Zinski, Steve]

We're starting to see a lot of spam in the 800KB to 1.2MB size range. I’m 
running MIMEdefang and it’s configured to skip messages larger than 100KB (and 
I hesitate to increase the limit due to performance issues). I read somewhere 
that there’s a way to have MIMEdefang (or spamassassin) strip out the non-text 
portions of the e-mail and scan. Can anyone help me set this up or point me in 
the right direction? Thanks!
