What's this ``cumulus''?  ``cumulus.stanford.edu''?  Where did you make
the ``IP alias'' for this machine?

If ``cumulus'' is a CNAME for d31jr0 (all in the proper domain and fully
qualified), it will all work fine.  And because domain names in mail
headers are supposed to be the ``real'' name and not some silly CNAME or
nickname or abbreviation, the machine that's doing the substitution is
playing by the correct rules.

Of course, your sendmail.cf will have to recognize mail to both host
names as local.
