Hi,
	I need the yacc and lex definitions for mail headers.
I don't know enough to ask correctly [by number] for what
I want.  If the yacc and lex grammers are not available, but
there is a source, or someone can tell me where [provide me
with] the definitions in plain text, I would be grateful.

	Basically I need to _prevent_ some machines on our
hub from mailing to others.  The routing is not so much the
point, but I need to be able to burst the headers destined
for rmail, and preform surgery on some.

	The real issue is that we have some destinations which
_do_ wnat mail, but only from certain sources, so I need to
become a guardian for these sites.

Rob.
