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

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

Sender Verify could refer to the "sender policy framework" (SPF, sometimes refered to as "sender ID").  It is a feature that's becoming popular now.  Has nothing to do with Domino -- you have to set up your public zone (DNS) files to indicate which servers are authorized to send messages on behalf of you e-Mail domains.

See http://spf.pobox.com

See also http://en.wikipedia.org/wiki/Sender_Policy_Framework for some detailed, almost-plain-English description.
