Unfortunately, Cobalt violates the tenet with their upgrade packages,
which have been known to update sendmail.cf without updating the .m4
files.  When we've installed this for clients we've always given them a
backup file of the original sendmail.cf as well.  And we always make
sure it works.

I'm sorry I was busy moving to a new office all this past week and
didn't have time to contribute to this thread.

But we go with changing sendmail.cf because Cobalt .m4 packages don't
always match their .m4 files.

The main problem with cut-and-paste is that cut-and-paste on many
platforms changes tabs to spaces.  If you restart sendmail manually from
the command line as Dan mentioned somewhere early in the thread, you'll
see it not start if you forget to change the spaces back to tabs.
