can't forward the email

[checcuccio]

Every time I try it report this error:

Error forwarding message 1 from l.romiti@xxxxx.it to f.martini@xxxxxx.it: Server rejected sender: 530 5.7.1 Client was not authenticated

Probably it is a setting in exchange but I can't solve it.
Can you help me?
Thanks

Hello,

Your Exchange server need to be configured to receive emails for the domain "xxxxxx.it", otherwise, it thinks you are trying to relay the message.

Here is an explanation about how to configure Exchange's Authoritative Domains: http://www.msexchange.org/tutorials/Exchange-2003-SMTP-Namespace-Sharing.html

I have the same problem, using Exchange 2007 SP1/Windows Server 2008.
I am only  using the trial version, testing it before to buy the full version.
If I understand the answer you gave, i have to declare ALL possible internet domain that might email me? Is there a way to just declare that you want to get all your emails 

Thank you,
Regards,
Emmanuel

No, it is not necessary (and not recommended) to enter the domain names of the sender's email address. What you need to enter is your domain name, so Exchange does not think that you are trying to relay.

For example, in our exchange server we would enter "eclarsys.com" as our authoritative domain.
