I have a sendmail problem on a Solaris client that I'm hoping you
experts can help me with. I've been banging my head on this for
several days. The client is running Solaris 10 6/06. I will show
the submit.mc and hostname.mc that were used to build the submit.cf
and sendmail.cf files below.
Users are logging in to a local unix host. This host should simply
forward it's mail to the mailhost in our domain. There are some
return address issues going on and also a delay in the mail being
sent and received (sometimes it's delayed and sometimes it doesn't
come through at all) if sent to a username that is unqualified.
Issue #1: if a user uses mailx to send email to users their return
address is often user@hostname.cs.bgsu.edu instead of
user@cs.bgsu.edu. The weird thing is this doesn't affect every
user. Nothing with respect to sendmail has been changed recently.
Issue #2: if users use mailx and send to a local domain user with an
unqualified address there is a delay in receiving the mail and
sometimes it never does make it through. Hmm, just tried again and
now it seems to be delayed even is I type mailx user@cs.bgsu.edu.
Just to note issues #1 and #2 are not affected by a user having a
.mailrc in their account.
Issue #3: Anyone who uses pine has no problems and it doesn't matter
if the username is unqualified or not.
I will admit right now that I don't 100% understand all the
intricacies of Sendmail. This problem has me stumped and in trying
to fix it I may have added directives into these files that don't
need to be there.
Thanks in advance for any suggestions.
Lisa
Here are the submit.mc and hostname.mc used to build the respective
submit.cf and sendmail.cf files.
