sounds like a sendmail config thing. Bummer.

Since I never learned the obscure syntax of the sendmail configuration
file I don't think I can help you other than to say:
http://www.postfix.org/

I've been told that once you figure out how the syntax of the sendmail
config file works that it is very flexible and easy to work with. Maybe
someone else on the list could provide some more insight...

I did feed some SMTP commands to your mail server with some interesting
results: 

---
$ nc mail.techalaska.com 25
220 sspeedy.techalaska.com ESMTP Sendmail 8.11.6/8.11.6; Wed, 26 Dec 2001 12:38:52 -0900

HELO akind.arctic.net
250 sspeedy.techalaska.com Hello akind.arctic.net [209.124.141.225],
pleased to meet you

MAIL FROM:james@thelostnet.net
250 2.1.0 james@thelostnet.net... Sender ok

RCPT TO:greg@techalaska.com
550 5.7.1 greg@techalaska.com... Relaying denied

RCPT TO:greg@sspeedy.techalaska.com
250 2.1.5 greg@sspeedy.techalaska.com... Recipient ok

Clearly, sendmail doesn't realize that it should be the final destination
for mail sent to 'techalaska.com'.  It is also advertising a host
'sspeedy.techalaska.com' that doesn't exist, this will cause problems when
you try to send mail.  Your mail server should advertise the hostname
resolved by a reverse lookup of your ip address, which is:

cable-186-3-237-24.anchorageak.net

and, your mail server should accept delivery of mail sent to
techalaska.com

If you can figure out how to make sendmail do those two things you are in.

hope that helps,

james
