How to configure IIS SMTP to forward ALL inbound email to ANOTHER domain


How does one configure IIS6 (Windows 2003 server) to forward ALL email to another domain?

I have a web application which runs on a web server.  This sends emails using CDO using the (fictitious) domain  For anti-spam filter reasons the MX record for points at this server.

I need to be able to forward all emails received to on to  E.g. sending an email to gets forwarded to which is hosted on a different ISP/Server.

I do not have Exchange;  it's a bog-standard IIS6 box running on the web server edition of W2k5.

Is this possible with IIS' SMTP server?  If not, recommendations please.

what you are describing is recipient address rewriting.

you can't do that with IIS smtp server.

there are plenty of alternatives - fee: mdaemon, mailenable, and many more.  free: postfix, sendmail, and many more.
