So what did your final configuration look like? -----Original Message----- From: John Burridge [mailto:JBurridge@xxxxxxxxx] Sent: Tuesday, November 13, 2001 8:39 AM To: [ISAserver.org Discussion List] Subject: [isalist] Re: ISA and SMTP http://www.ISAserver.org And it actually worked - I had a smart host that I didnt need. -----Original Message----- From: John Burridge [mailto:JBurridge@xxxxxxxxx] Sent: 13 November 2001 13:29 To: [ISAserver.org Discussion List] Subject: [isalist] Re: ISA and SMTP http://www.ISAserver.org I am using Exchange 5.5. If I already have a Internet connector, can I make another SMTP connection? On the assumption I cant, I have created a zone for my e-mail address, and in that have placed an MX record pointing to my exchange server. When I go to the other server with the SMTP service on it, and do an nslookup (set type=mx), I get the correct internal address, yet still the mail does not leave the queue. Am I missing anything?

Make an SMTP connector between them. It's all in the Exchange docs... ISA isn't going to allow that kind of traffic (14120-error), because it makes no sense to send packets to the external interface if they never should have left the internal network to begin with.

If the server is internal, let it make an internal request.

This has worked fine for SMTP mail. The problem I am having, is that I have another internal SMTP server. This server delivers mail properly to all external adresses but not the ones on my exchange server. When I telnet to any external SMTP server from this server it works fine, but when I telnet to my exchange server using the IP of the external NIC on my ISA server it does not work. Does anyone have a work around?
