550 relay not permitted Valid RCPT command must precede DATA


I have configured Sendmail and POP3 on my mail server. I have been able to send mail to outside domains but have not been able to receive mail from them. I get a message as follows:

The original message was received at Tue, 4 Mar 2008 16:15:33 +0200
from otherdomain.com [192.168.1.1]

----- The following addresses had permanent fatal errors -----
<webmaster@mydomain.com>
(reason: 550 relay not permitted)

----- Transcript of session follows -----
... while talking to mx0.myisp.com.:
>>> DATA
<<< 550 relay not permitted
550 5.1.1 <webmaster@mydomain.com>... User unknown
<<< 503-All RCPT commands were rejected with this error:
<<< 503-relay not permitted
<<< 503 Valid RCPT command must precede DATA

I have used fictional domain for privacy. What could be the problem? Assistance will be greatly appreciated.
