I don't mean to sound like we're ganging up on you, Claude, but - yeah,
that seems to be the broken component in the communication here. Not
horribly broken, since you seem to eventually follow the advice that's
given, but it does take several repetitions. Now, Rick and I both get
paid large amounts of^W^W^Wnot enough money to do this professionally; I
can't speak for him, but from my perspective, giving advice *without
charge* and having it ignored is pretty galling. I'd appreciate it if
you would not do that anymore.

I realize that it's been a lot of new information and things to do - but
I assure you that paying careful attention to what's been said will
greatly reduce the amount of labor necessary, while ignoring it will
multiply it by a large factor. This is part of the reason that this
process has taken so long.

To summarize: your mail server (mail.suttonmachine.net/2it.net) is
broken in that it doesn't know who "suttonmachine.com" is - see that
"Relaying denied" message? It also doesn't know anything about a user
named "claudesutton". Therefore, every time you try to send mail to
"claudesutton at suttonmachine.com", you're going to get a DSN telling you
that there's a problem - and you keep including that address in the CC
list when you send us mail.

That, as far as I can tell, covers the entire situation.
