You should examine the log files in /var/log/maillog,
isolate the exact error message, and then post it.

Assuming you're using sendmail, I would check the file

    /etc/mail/sendmail.cf

for the value of the relay

    # "Smart" relay host (may be null)
    DS

and see if it's set a value which makes sense
for your situation.
