Only when i forward emails with attachements "550 relaying mail to" [domain] "is not allowed"

[Alchemy]

G'day hope someone can help........

I have an WIN XPSP2 using MS Office 2K3 Outlook SP2 as the default
email editior (using a POP3 mailbox) all MS updates have been installed
and configured.

However whenever i forward an mail with an attachement I recieve a "550
relaying mail to" [domain] "is not allowed".

I can create a new copy of the original email, attach the original
attachment and the email is successfully delievered.

FYI - My ISP hosts is also my mail host.

I'd appreciate any assistance

With Regards

Alchemy

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

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.

Given this, the first thing to do is make sure you disable any email
scanning by your antivirus program.

Try disabling antivirus or firewall. If you are connected via a Router try
bypassing the router and sending the email.
