Sam,

I think there might be a small problem with courier. I'm only guessing
here. Let me put out my information. Maybe you can make more sense of it
since you are so much more familiar with the code and operations of courier
than I am.

First, I tried to manually connect and send an email to the relay. Here is
the log of that.

note: Recipient domain has been replaced with yyy. it's actually "dga" in
the mail.

--------------------------------
This email did get delivered to my inbox.

Now, immediately after, I set my esmtproutes to be
:k2smtpout.secureserver.net
then sent a mail from local mail client to blong@yyy.org. I captured a
tcpdump of the traffic with host k2smtpout.secureserver.net

First, is a dump of my maillog for that transaction.

It failed.

Using the capture file, I opened it up in ethereal and did a follow stream.
here's the output of that.

220 k2smtpout02-01.prod.mesa1.secureservEHLO mail.longboys.net
250-k2smtpout02-01.prod.mesa1.secureserv250-AUTH LOGIN PLAIN

250 MAIL FROM:<bitman@longboys.net> BODY=7BI250 Sender accepted.
RCPT TO:<blong@yyy.org>
DATA
553 Sorry, that domain isn't in my list 503 You must send RCPT TO: first

I noticed that the RCPT TO:<blong@yyy.org> had the DATA follow without a
response from the k2smtpout server. I double checked the stream in ethereal
and indeed courier did send the data command immediately after sending the
RCPT TO without waiting for a 250 response from the server.

This would actually be consistent with the error message. If courier was
sending the DATA command while the server was still looking for a RCPT TO,
then DATA would be part of the domain name, and would definitely show up as
an invalid domain.

any ideas? any help or ideas you can give would be most appreciated.
