[comp.mail.sendmail] Sendmail vs. changing Internet Domain Name

dct@mdaali.mda.uth.tmc.edu (David C. Tuttle) (04/05/91)

I need help telling sendmail that we should be getting mail under two 
different host.domain names.

We recently changed our Internet domain name, and made appropriate changes 
everywhere (we hope :-), including sendmail.cf.  The problem is, mail 
addressed to the *old* address bounces due to "service unavailable".

Here is a look at what I (as postmaster) get:
(The old domain is "cancer.utexas.edu", the new one is "mda.uth.tmc.edu")

     ----- Transcript of session follows -----
  Connected to mdaali.cancer.utexas.edu:
  >>> HELO mdaali.mda.uth.tmc.edu
  <<< 553 mdaali.mda.uth.tmc.edu host name configuration error
  554 <an12366@mdaali.cancer.utexas.edu>... Service unavailable

We have set "Dwmdaali.mda.uth.tmc.edu"
Setting "Cwmdaali.cancer.utexas.edu mdaali.mda.uth.tmc.edu", as was
suggested to me, didn't change things.

I don't have great knowledge of these things, and the manual is its
usual cryptic self.  I'd appreciate getting an e-mail (to the new address 
(which works, thank goodness)) and I'll summarize answers.  Please help us 
stop bouncing most of our mail!
