Good Idea.

We should'nt filter out all mail with MIME enclosures, as occasionally MIME 
enclosures are validly used on FreeBSD lists, But to list a few WIBNIs:
(WIBNI = Woundn't It Be Nice If )

We could bounce/kill all postings containing MIME with .exe spam.
 (We have uuencode in the rare event we need to broadcast a binary.)

We could bounce/kill postings containing MIME with .doc enclosures, stopping:
 more spam & EG non Unix oriented people dumping .doc resumes on jobs@freebsd.
 OK, it would also reject .doc format job adverts, some may not like that,
 but if a company is so uncaring/incompetent they can't even reformat a
 bounced .doc in ascii or some public format, I'm not interested.

We could also bounce/kill postings containing 
	Content-Type: text/html; charset=big5
& other non latin fonts, as we all use latin fonts on freebsd lists,
it being the only one we all understand.  Sure some people set 
	charset=big5
by mistake (& then send ascii anyway), & they are discussing real FreeBSD
issues, but it'd cut spam from non latin charset originators.

We could also bounce/kill postings containing possibly auto-load HREFs ?
(Do they exist as such ? I got one direct, not from a BSD list, 
looks rather innocuous initially, starting:

(BTW It doesnt work, geocities says kino33us/por.css doesnt exist,
 though the spam is not old:

Anyone who could give postmaster@freebsd.org filter mechanisms that
freebsd.org could integrate to reduce spam on lists, would be a minor hero :-)
