Activation emails and new post emails are sent successfully, however, when an email is sent from one user to another user, the sender receives an errored email message with a message like this:

Quote:The original message was received at Wed, 27 May 2009 13:23:03 -0400
from localhost.localdomain [127.0.0.1]

----- The following addresses had permanent fatal errors -----
<[email protected]>
(reason: 553 sorry, sender mail address must correspond to local mail domain (#5.7.1))

Has anyone encountered this and have any suggestions to resolve?

Thanks!
