A friend is trying to set up a Postfix submit server on port 587, so

This is surely a FAQ, but we must both be very nearsighted because we
can't find it. Can someone remind us where it explains how to set up
a SUBMIT server with a different config from one's regular server?
Tnx,

The general docs are here
http://www.postfix.org/master.5.html
and there is a commented-out minimal submission service
example in the default master.cf.
You'll want something like this, season to taste:
# master.cf
# this first line is a copy of the "smtp...smtpd" service
submission inet n - n - - smtpd
# subsequent indented lines override main.cf settings.
