As it is you should turn it off on port 80/443 if you use, for instance,
acid.

Interesting - this email exchange triggered this rule in my
system, giving me a moment's heart palpatation.  :)  It saw it on
port 25 - so I knew it was either legit email, or a new hack of
sendmail.

I'll probably add a new rule to turn this off if on port 25 or
I'll get more similar false positives.  I'm not sure how to
trigger on it on port 25 if it's not in email....  gotta think
about that.
