The trouble is it WON'T try to talk to the exchanger, it wants to talk to the non-networked site. B^(. I guess I should clearify. I'll use REAL site names. Say I want to mail to joe@bungia.mn.org. a.cs.uiuc.edu HAS an MX record for mn.org and thus can be used as a gateway to it. HOW do I tell sendmail it should contact a.cs.uiuc.edu rather than bungia.mn.org. bungia.mn.org is a CORRECT canonical name it just doesn't have an SMTP connection. CAN sendmail find out that a.cs.uiuc.edu is the mail exchanger for bungia.mn.org and, finding that out, can it talk to a.cs.uiuc.edu rather than sending out a connect request to bungia.mn.org, a site that isn't directly on the net. Right now, no matter what I try, sendmail wants to talk to the non-networked site, NOT the mail exchanger. How do I get sendmail to talk to the right machine? I thank Mr. Zeilenga for his comments and hope that my clearification explains better the question I was asking. -Rob Healey rhealey@ub.d.umn.edu
