No and no...and I might add that just because the bat book says it should
be so doesn't make it a good reference.  To my knowledge no current standard
requires such lines (nothing in RFC821, RFC822, or RFC1123 in any case).
The bat book is simply trying to make a case for something the sendmail
author has decided is a Good Thing (the "well-designed program" mentioned
specifically in the bat book is vacation(1), which the sendmail author also
wrote).  The bottom line is that it is not difficult to determine that a
message is coming from a mailing list and that it should not be responded
to by a vacation daemon.  We've discussed this before on this list...
