First, thanks to Tim and to everyone else who has responded to my
inquiry. Unlike some of the people on the list, I am *not* a Un*x
heavy. Sometimes people more or less get dumped onto a system without
instruction and not even always a good idea where to start looking (or
even to find the FM if they knew what FM to RT. :) )

Why would grep be better than egrep here? (And I can't find a
switch which will tell me whether it is a GNU or not.)
WHOFROM=`formail -rtx'To:' | sed "s/.*<//;s/>.*//"`
Whould this handle the case you mention below?
> user(_at_)domain (Foo Bar)
But why not just make the userlist file a name of "email addresses proper"
only? That way, no matter it would make no difference whether the "From:"
line was
As I mentioned in my original post, the form of the userlist file is
user1(_at_)domain1, user2(_at_)domain2, user3(_at_)domain3, etc.
strung out in a single record. I may be displaying my ignorance here.
If all tests pass, eventually $USERLIST is going to get fed into the
Bcc: field of an outgoing mail via formail, one of the fields of which
being
-I "Bcc:" `cat $USERLIST`
If this will even work. One respondent suggested that I make the user
file one address per line. Unfortunately I do not know whether that
will work with sendmail as a Bcc: (i.e., with no comma after each
address and with newlines after each). I do not have addresses
available to me for trying it out.
and you could run into problems with the above WHOFROM if someone formatted
their email address like this:
user(_at_)domain (Foo Bar)
Thank you. I had not thought of that. It all comes down to this:
1) I need to get the user(_at_)domain out of From:, stripped clean of the
nonessentials; 2) I need to determine whether user(_at_)domain is within
a list of permissible addresses; 3) If it is, I need to generate a
mail with all members of the permissible list Bcc'ed; 4) It would be
very nice if I only had to maintain one list (i.e., both for
permissibility lookup and for feeding into Bcc:.)
(BTW, this whole recipe is still fluid, which is why I have not
taken up space posting it here.)
