Mail bounces & wont send

[cmdickey]

Whenever I try to send email to my virtual hosting server, it comes back saying that the following recepient address(es) failed. On the server, when I send mail from horde / squirrelmail, nothing sends. If I try to send it from the local system as one of the users with the following command, it comes through. What's the deal?

# echo "test" | mail -s "This is a test" support@XXXXX.com

Here are the exim logs, if it helps at all
