Open relay

Hello,

I'm writing a service which its purpose is something like mail
filtering.
user
user1 @a.com sends a msg to user @myserver.com, and i pass it to user3
@b.com (after filtering it) where b.com can be ANY SERVER in the world.
is there a way to do this
without open relay? (i understood that open relay might be considered
spamming)

i'm using iis 6.0's smtp server.

thanks

Yes,

You have to define for your SMTP service which domains are valid to
accept. I believe there are drop in modules for Exchange and possibly
the service you use that would proxy the connection and hand of the
"good" message to the SMTP service.
