Thanks for replying Brian, however, I'm not sure how to go about
resolving this "authenticating to the outgoing server" issue. Hope
that you might be able to provide some further pointers.

Bear in mind, the problem only occurs with emails that are forwarded
with an attachment. Emails forwarded that don't have attachements are
sent and delievered to their respective recipients without any problem.
With one exception..... If I forward an email with an attachment to a
recipient on the same email domain, no problems are encountered.

Thanks for any further thoughts.

With Regards

Alchemy

However whenever i forward an mail with an attachement I recieve a

Usually the result of not properly authenticating to the outgoing server.
