It looks like *your* mail server is not properly advertising what your domain is.  This information needs to be in your EHLO/HELO to them.  The reason for rejection is that the intended recipient thinks that your mail server is acting as a relayer of spam messages.

Look at sembee's (accepted) comment on this Q

http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/Q_23037415.html

You will need to change the name to match the setting used by DNS that delivers mail to your domain.  Use DNSStuff to verify what that address is.

http://member.dnsstuff.com/pages/tools.php

Use the DNSlookup tool (3rd column, 2nd row down), type your domain in the big box and choose MX record in the second box, press the Lookup button.  

There may be several Answers, usually the one you will be interested in is the top one.  This will be the value you will need to insert.

For some reason, the Exchange setup skips this obvious question and nearly every person runs into this with their first Exchange implementation. The default is either machine.domain.local (note the local), localhost or the ISP (as it looks like in this case - dsl.com)

Much more common than the MX record, although that also needs to be checked.

If you don't have a domain, you can use Smart Host and have Exchange send via your ISP's smtp server

:-(

I really dislike the .local default... we check the IP address for email as part of our spam check.

The number of exceptions we've had to make for small sites who just don't change this is really annoying.
