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 Matthew Loraditch
