Newbie MX problem

[chris at tourneyland.com]

Hi all,

I have a domain named 'tourneyland.net', and I've added an MX line in my
datafile that says this:

tourneyland.net.	MX	10 lurch

where lurch is my mail hub. The problem is, sending to e.g.
chris at tourneyland.net results in this error:

  554 MX list for tourneyland.net. points back to lurch.tourneyland.net
  554 <chris at tourneyland.net>... Local configuration error

I searched the archives for this, and I found a the same question raised
just a few days ago. The answer was that his mail hub wasn't set up for
relaying, and mine isn't either. However, could anyone explain the problem
in a little greater detail? I'd like to actually know what's going on at
lurch when the email is sent.

I assume the problem is this:

1) By default lurch isn't going to accept amil to anyone except
lurch.tourneyland.net, so it's going to reject requests to process email
sent to chris at tourneyland.net

2) By changing lurch's sendmail.cf, I can fix that

I'm guessing that I fix thsat through the Cw (or Fw)
directive/command/whatever.

Is this the case? If what I have is 100% a sendmail problem, then I'll take
it from there.

Thanks,
Chris
