I kicked up a 'test' rule for this last night, and it one lit up my logs on 
all the incoming copies, might be of use to some of you.

alert tcp any 110 -> any any (msg:"BETA--BadTrans.B Detected--"; 
content:"audio/x-wav"; content:"ABC1234567890DEF"; nocase;)

I like it because the alerts contain the full header, as well as the 
attachment name.  (nice to watch for alterations to the strain).
