Well,
I got this on the Dragon list and it seems that no rule for Mimail
exists for Snort yet. ;)

I guess something like the below would do:

alert tcp $EXTERNAL_NET any -> $SMTP_SERVERS 25 (msg:"MIMAIL-Virus";
flow:to_server,established; content:"This email address will be exp";
classtype:bad-unknown; sid:1000091; rev:1;)

with regards,
-bd

i've found this one is pretty accurate, haven't seen false positives yet on it
(operative word, "yet").
