Are these domains within the same network. I had a case like that where all mail was being routed to my DC which accidentally had SMTP installed on it. After I stopped SMTP it went down the line to the next. We were able to find that by using network monitor to capture the data. Allow connections from: All except the list below. Allow Relaying for: Only the list below (list blank) Customer has external name resolution with internal DNS servers, but has put External DNS servers in the virtual server. Had customer remove these entries. These were the settings Microsoft had me set to stop the relaying.

When I run through the telnet process, I get 250 2.1.5 username@xxxxxxxxxx <mailto:username@xxxxxxxxxx> . I also looked at article 324958 to try and fix the problem and after following this article I still have this problem. I added another connector. One connector has the default settings on there, in the address space tab the box at the bottom is cleared. In the other connector, I have the domain in there that I'm relaying and I have the box at the bottom of the address space tab checked. -----Original Message----- From: Mark Fugatt [mailto:mark@xxxxxxxxx] Sent: Thursday, February 20, 2003 10:38 AM To: [ExchangeList] Subject: [exchangelist] Re: Open Relay - Revisit - http://www.MSExchange.org/ John, If this is Exchange 2000 create two connectors one with the default and then checkbox cleared, the other with the two domain you relay for with the checkbox checked.
