[comp.sys.next] Sendmail problem and talk question

prophet@oxy.edu (Dale Bruce LaFountain) (05/30/91)

I have been trying to set up a NeXT cube and one NeXTStation in a
subdomain, and have been experiencing many problems with mail.
Until we (the two NeXTs) got moved into this subdomain, everything
worked fine, I would guess due to our nameserver and mail-relay being
in the same domain.  Now I can't get cub (the cube) to put a fully
qualified domain name on the From: line.  For example, if I send mail
from my account prophet@cub.math.oxy.edu, the From: line reads only
prophet@cub.  I had to edit the sendmail.cf file to recognize itself
(add the full domains to ruleset 6), but I haven't seen how to make
cub export it's full domain name.  It was suggested to me that I merely
change the hostname from cub to cub.math.oxy.edu, but I have a feeling
that is not a solution.  It sounds more like a workaround that ignores
the problem.  I am also having problems sending mail to the new domain
name (cub.math.oxy.edu), although it accepts cub.oxy.edu without any
complaints.  If it matters at all, the NeXTStation is set up as a mail
client, and I have added its domain name(s) to the self-identifying part
of ruleset 6.

Is this a generic problem with the packaged sendmail.cf files?	If so,
could someone _please_ send me a corrected version or pointers on how to
remedy these problems?

My other question has to do with talk.	I can't get it to work across the
network to non-NeXT machines (a Sun3/60 to be specific).  I get the message
'Host is too refused (sic) to talk to us.'  I can talk between two NeXTs
fine, but moving out of NeXTdom doesn't wash.  Is there a way to 'register
my invitation' with the NeXT so I can 'talk' to it from our Sun?

Any help would be greatly appreciated.
