On the exchange IMC you need to set it to do forwarding to the IIS server. And IIS server SMTP setting you need to add in your email domain in it and forward it back to the exhange server. And also allow the ip address of the exchange to relay to the IIS server only. Test needs to be done. 1) Telnet from the exchange to the IIS server on port 25 . Make sure it give you teh reply. 2) Telnet from the IIS server to the exchange server on port 25 also. -----Original Message----- From: jibarra@xxxxxxxxxxx [mailto:jibarra@xxxxxxxxxxx] Sent: Fri 3/22/2002 12:03 AM To: [ExchangeList] Cc: Subject: [exchangelist] Relaying http://www.MSExchange.org/ Hello, to all, I am running Exchange 5.5 and my question is the following. My web server needs to send out emails to certain people internally when an update has been made. For some reason the mail never makes it to its destination and its been queued in my SMTP server. How can I tell my exchange server to allow relaying from my web server, so that it allows it to send the email. Any input will be appreciated. thanks, Juan ------------------------------------------------------ You are currently subscribed to this MSExchange.org Discussion List as: andyching@xxxxxxxxxxxxx To unsubscribe send a blank email to leave-exchangelist-495973J@xxxxxxxxxxxxx
