I don't think that is what's going on here. I am fairly convinced he's 
**NOT** touching the source at all. I will not take the time to verify
this by ploughing through the entire build to see if any .m4 files he
IS hacking are used in the buils itself. Why? I've got better things to
do; this will be WORK! :)

Earlier, I had written:

Adam!
  1. Don't hold back on your feelings on this topic, please! We want to
     know how you REALLY feel! :)
  2. Admittedly, he's not touching source. What he is doing is patching
     up .m4 files a LOT more deeply than merely adding or modifying a few
     fairly simple declaritive macros in sendmail.mc

I'm sure it works for him. I'm lso sure he writes "sendmail" in that little
box on the tax form where it say "occupation"! :)

My problems have mostly been difficulty with understanding how particular 
features interact, and in figuring out whether my sense of "local" or "remote"
matches the documentation. Other than that, I make the usual mistakes any M4
novice might have made.
