Try setting the smtp server field with ip address rather than hostname.

Hi...Guys..
No more sugessions??????????

Deva
Its an SMTP error, so the receiving host did not  accept the message as there might be something abt the  senders address that it could not handle, It might be a anti-spam or anti-relay etc etc

also debug using the notes.ini's SMTPDebug and SMTPDebugIO and post what is coming in the console
