SMTP mail from server error, except for recipients with the same domain name as server? (PasswordRe)

The error below can be reproduced by visiting


http://www.xeowoolfe.com/xw_profile/xw_login.aspx


and trying to recover/reset the password for Chris. (Secret Q: 1, Ans: 2)Chris has an optusnet.com.au email address (which is real and valid.)


However, if you do a password reset for Bruce(Q 1, A 2) , who has an email address of [email protected], then it works okay!!??


xeowoolfe.com is a pointed domain, it points to hypothetico-deductive.info (in our Web 'cluster'.) Mail server is mail.hypothetico-deductive.info.


Note - both users are me.


How do I get the server to accept the recipient addresses. This problem doesn't occur with a standard contact page using smtpclient. I wonder what is different about the PasswordRecovery control that causes the problem??


Ta Much,





Bruce.
