This will work, provided that the command "postconf mydomain"
outputs "ece.northwestern.edu". Postfix will then send your mail
to one of the MX hosts for ece.northwestern.edu:
domain name ttl resource-type priority mailhost
=========================================================================
ece.northwestern.edu. 14400 IN MX 10 ncore.ece.northwestern.edu.
ece.northwestern.edu. 14400 IN MX 10 nncore.ece.northwestern.edu.
ece.northwestern.edu. 14400 IN MX 20 ajax.ece.northwestern.edu.
And, as long as these hosts accept your mail, all will be well.
