- Summary: Why aren't MX record names fully expanded?

-
- All right, I really like this IDA sendmail stuff. The reason I like
- it is that I don't know that much about sendmail and cf files. I
- have a small problem with my configuration (and therefore I can't
- figure this out myself).
-
- Our campus uses MX records a bunch. Doing address testing reveals
- that sendmail treats MX records somewhat differently than A records.
- 'casbah' is a host on campus (the MX record 'gtri' points to casbah).
-
- Sending mail to either 'foobar@casbah.gatech.edu' or 'foobar@casbah'
- works just fine. It looks like ruleset 8 figures out to tack .gatech.edu
- to the end of a single hostname.
-
- Sending to 'foobar@gtri.gatech.edu' works too. It's 'foobar@gtri' that
- fails. In this case no ruleset (including 8) tries to attach a
- '.gatech.edu' to the end. Thus, sendmail just punts to the campus
- central mail server (which happens to be gatech.edu). The typescript
- of the 4 example addresses are attached followed by my M4 file.
-
- Is this a problem with my M4 file, the master cf file or has some-
- one set up the campus name server incorrectly? Any help is appreciated.
- (I *know* many people will just type addresses of the form foo@gtri
- when sending mail and I just can't see making all that mail get
- punted unnecessarily).
-
- Thanks,
- Robert
-
- PS Also, 'foobar@anything.gatech' punts to the central server. Is
- there a way to make this work too (get sendmail to figure out
- how to add the .edu)?
