This is probably a simple minded sendmail question, but here goes...

How does sendmail (on machine A) determine if a particular user exists
on that machine (when receiving mail for delivery)?  There are two
considerations here:

	1.  Will it just (blindly) write the message to /var/spool/mail
	    without consulting anything?  Or, what does it consult?

	2.  How (assuming it accepts the message) does it determine the
	    location of the home directory for that user in order to
	    consult the .forward file?

Here is the scenario.  SunOS 4.x running YP, so that there are no local
passwd or aliases files.  We want all mail to go to mailhost and then
mount /var/spool/mail on the clients.  The problem I imagine here is that
home directories not on mailhost won't be searched for .forward.  (We
do run the automounter.)

Is any of this possible?  (or is this a stupid question?)

Thanks for your attention,
Robert
(reply via mail is adequate)
