[Mimedefang] Mimedefang 2.36 and how to drop a blocked attachment message - action_bounce?

[Schuyler Bishop]

I've seen a few messages somewhat relating to this in the archives but
nothing with an authoritative answer.  Apologies if you feel it's a newbie
repeat.  ^_^

After a few iterations of perl upgrades, many CPAN module installs,
sendmail recopiles and other standard challenges, I got mimedefang
working.  Celebrations aside, I'm trying to see how difficult it would be
to just delete the e-mail, or bounce it with an error?  The problem I've
had is I have mailman lists where the e-mail address for the list has to
be posted on the website so every e-mail bomb ever grabs it and I get
hundreds of blaster, sobig, etc infected messages per day sometimes.  I'm
sure you all have much exaggerated versions of this. ;)

Granted, mimedefang now removes the harmful part of them but I sure would
rather not have to add a header line, change my .procmailrc (and mailman)
to filter those, etc.  It'd be better for them to just go away.

It seems that using action_bounce for - well - everything but spam - would
handle this nicely at the SMTP level and I just wanted to verify that
doesn't have any unwanted "challenges".  Where should this change take
place in the filter file?

Thanks in advance.
