Error creating new domain account

[RobertS]

When I create an new account I get the following error:
Unable to send notification: mail() failed: SMTP server responce: 550 Requested action not taken: mailbox unavailable or not local

I am running Plesk 7.5.6 and I have this problem since a few days, nothing is changed in my setup

Who knows this problem and a solution to it?

Please check e-mail in Plesk - Server - Edit, Notification. It should be a real address. Send to it a test message.
