Sounds like you edited sendmail.cf directly. That's not the standard
configuration file for local changes, those usually live in
sendmail.mc and are processed with the m4 macro language. As I
remember sendmail from.... oh, a very long time ago, you need to use
the "sendmail.fc" or "frozen configuration" config file if you want to
protect it from rebuilds based on sendmail.mc.

Personally, I gave up on sendmail in favor of postfix a decade ago.
The only reason I use anything other than postfix these days is if I
want to have /etc/aliases and procmail read for local email addresses,
and SMTP relay for 'name at host.com' email addresses. The only SMTP
server I've seen that handles both at the same time  is exim.
