[Mimedefang] RFC822 From: header

[Paul Whittney]

It's nice to see the MIMEDefang way of getting this, but it seems
that with the level of processing you want to do, and multiple
addresses, isn't the access database of sendmail the correct place?

You can even leave sendmail running when you put the access.db file
on the server (and if you use CVS, backtracking, and logging what and
why you're doing this isn't a bad idea either).

http://www.sendmail.org/m4/anti_spam.html#access_db

Sometimes I've even used:
person at somewhere.local	ERROR:"550 Denied. Please call: 123 345 6786"
site.idontwant.local	REJECT

I admit, regular expressions are a good reason to have it in MIMEDefang.

Not sure which is better... thoughts? 

Um, or have I missed the point somewhere?
