Usually the RPM won't replace these files (and it doesn't in all my installs).
I think the problem is that you are using symlinks. Just replace the files.
Make sure to replace or empty sendmail.mc as well, as restarting sendmail
will rebuild sendmail.cf from sendmail.mc.
The submit.mc and submit.cf files are used for users submitting mail through
the sendmail binary. If you really need it changed, treat it similarly to
the sendmail.mc and sendmail.cf files above.
