Unable to send mail to self 550 5.7.1 unable to relay

Hello everyone,

I'm fairly new to Exchange so this may be a trivial fix.

I've installed SBS 2011 with Exchange 2010 however I cannot send mails, even back to myself, without getting a 5.7.1 unable to relay error.  When connecting to remote.mydomain.net I can log in through OWA and it sends/receives mail perfectly.  Logging in through telnet to my server to send mail results in the same unable to relay error. 

If anyone knows how to move forward on this issue I'd greatly appreciate it!

Thanks in advance
