Mail query

	I am running into a problem with my mail system under 4.1 BSD UNIX.
Many sites send us mail with lines like:

Reply-To: "Bozo" <bozo at clown>

	When we try to reply to such a message our mail system tries to do
something with "Bozo" rather than just ignoring it.  Now I have copies of
RFC733 (21-Nov-1977) and RFC822 (13-Aug-1985), which supercedes RFC733, and
both RFC's seem to support the "Bozo" <bozo at clown> format.  Am I correct
that both RFC's support this format, and on the Reply-To: line to boot?
Is it a bug that 4.1 BSD UNIX does not support this format, or is really
just that someone has put a new feature into the mail headers that was not
supported way back when we got 4.1 BSD, and so I'm just really behind the
times?  (The effect is the same.)

	I have source for 4.1 BSD UNIX, and I think I could change the
routine "skin" in the file /usr/src/cmd/ucbmail/aux.c to handle (ignore)
the "Bozo" type of stuff.  But don't I have to watch out for things like

Reply-To: "Big Gut"@tumtum

where the quoted stuff is important?

Thanks.
