With simple null-clients you can stop after setting up the
null-client without adding an MTA instance.

With "myorigin" remote, rewriting needs to use virtual(5) not
aliases(5), as explained in the null-client example.

Local aliases have no effect on mail that is relayed, rather

P.S. The stanford.edu domain is one of the few .edu domains with
DNSSEC enabled. I'd like to see Stanford be the first ".edu"
with DANE TLSA records. The postmaster for stanford.edu can
contacting me off-list for guidance if there any questions.
