Creating new client error

I get this error message when creating new client:

Warning: Unable to send notification: mail() failed: mail() [<a href='function.mail'>function.mail</a>]: SMTP server response: 550 Requested action not taken: mailbox unavailable or not local

Any ideas????
 
smtp auth

The "no such user" or mailbox not available error message is caused when u have not enabled SMTP authentication. You should allow relay for localhost in ur mailserver to correct the issue
