  Looks good to me.

  In my SMTP configs, I don't have an "M:LOGIN" line, but I have no
idea what that does, so maybe it's needed with DynDNS, or some
distros, or maybe it's just making a default explicit, or whatever.
Presumably one should include it.

  One still needs the sendmail-cf package installed, but on hat-like
systems (including CentOS), one can just do:

	make -C /etc/mail

and it will automatically build all the needed files, databases, maps,
and so on.  (There's a Makefile in the /etc/mail directory, and the -C
just tells make(1) to look there.)

  Sendmail runs an MSA (Mail Submission Agent -- "SMTP lite") on
TCP/587 by default, but hat-like systems shut that off by default,
too.  Their stock sendmail.mc macro config file does have a commented
out line which seems intended to turn this back on.  Removing the
comment-out, it would be:

	DAEMON_OPTIONS(`Port=submission, Name=MSA, M=Ea')

  Run make, restart Sendmail, adjust any firewall rules, and one
should be all set.
