I have my primary domain which is home@xxxxxxxxxxxxxx and then we have a
small group of about 10 users who have their own domain. Well, we are
now routing they're mail for them on our server. Does that make sense? I
don't know if I'm using the right terminology or not.

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.

        Mark, I followed your article and I did a test and found out
that I'm an open relay. 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.

        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.
