SMTP Relay Setup Matthew Loraditch

iis smtp nntp: Does anyone know of any good tutorials on setting up a smtp server in the
following situation. I think i have my setup right and i want to see what i
may have done wrong
I have one server that i use for inbound mail filtering for spam (WEBSERVER)
and av and then my exchange server. (EXCHANGE)
My internet mx says send all email to WEBSERVER.MYDOM.COM. This server is
AFAIK successfully receiving email sent from outside. WEBSERVER filters the
email and then sends to EXCHANGE.MYDOM.COM.
WEBSERVER has my domain setup as a remote domain and set to forward using
smarthost, the ip of EXCHANGE is entered in brackets in the box. I also have
the allow incoming email to be relayed to this domain box checked. On
EXCHANGE I have the IP of WEBSERVER in the allow relay settings. When
WEBSERVER tries to send email to EXCHANGE I do see a connected session in
the current sessions view, that session will last as long as my timeout
settings allow (10 minutes). After which the connection is dropped and i get
and Event ID 4006 on WEBSERVER: Message delivery to the host '10.x.x.x'
failed while delivering to the remote domain 'MYDOM.COM' for the following
reason: The connection was dropped by the remote host.
What have i done wrong? what do i need to fix?
Thanks

Hi,

From your post it appears that you have configured everything correct (you
don't need to allow the webserver to relay thru the exchange server but that
shouldn't cause the problem you are seeing).

You have configured 'MYDOM.COM' in a recipient policy on the exchange
server?

Yes, until i setup this new filter server all mail was going directly to my
exchange server and was being received perfectly fine. This really perplexes
me. Shouldn't EXCHANGE just be seeing WEBSERVER as any other mail server?
Thanks
