[rancid] Email notification problems.

What it comes down to is that the mxhost (outside) for that domain is going away.  This message is being generated inside.  I could spend a lot of time rewriting the header or renaming the domain within rancid from the short one to the long one, but I think I will just let it deliver.  It uses our internal relay which we won't deny for the short domain.  I had the rule that was barking about the short domain's demise excluded from the rancid server, and it's all good again.  Maybe I should suggest to the email admin that he should apply that rule only to email that enters from outside, since inside email to the short domain will still deliver.  

Thanks again.  I did try to use the rancid.conf's MAILDOMAIN setting, but it didn't work for me.  Not sure why.

Something about this rings familiar, but it was a long time ago and on Postfix, not Sendmail.

IIRC it was a combination of domain rewrite rules in Postfix's conf, and the local hostname was set wrong in /etc/hosts.

Anything relevant in your mail logs?

But what happens is that even though I send the message in aliases.db to username at longdomain.com, the From: field remains rancid-routers at rancid.shortdomain.com.  It's hard for me to know if this is a sending MTA issue or a receiving MTA issue.  It appears in the headers that the mail is being resent from the right username at longname.com domain, but the delivery address remains rancid-switches at rancid.shortname.com still.  I'm not sure of the impact of recompiling the package replacing shortname.com with the longname.com domain name.  I wonder if it would cause havoc in the CVS or other systems.  I'm guessing that I might be able to do some magic in the sendmail.cf file...  Just not sure where.  Make all delivery messages of shortname.com be rewritten with longname.com instead.
