I have setup a new echange 2010 server and everything is working fine except some emails that i had setup to go to my old exchange server on port 2525.

How do I create a seond smpt listen port in Exchange 2010 and server 2008 so these come through.


Thanks

you need to create an additional receive connector

Open EMC goto Server Configuration -> Server -> ReciveConnectors and add a new connector that listens on port 2525 (tab network)

addionaly you need to make sure that you open the port in windows firewall if your firewall is running.

Ok  I have gone in and done this but I cannot telnet to this port.  I made it an Internet port because it will be emails from the outside world.

Here is what I am trying to do.

I have my exchange 2010 server and an Exchange 2003 server.  All mail used to go to teh Exchange 2003 server but now that I have implemented my Exchange 2010 server all mail goes through it and delivers to my Exchange 2003 server.  Now for some reason I cannot get emails the are sent to us from our remote systems sending to mail.XXXX.com:2525

You need to have a routing group connector between Ex2010 and exchange 2003. No send connectors - smarthost to any port between them !
you can figure that out from exch 2003 ESM !
Just want to know .. why 2525?

Everyone here is the deal.

I am able to receive emails with no issues when emails are sent to my company using hotmail etc.  They route to my exchange 2010 server and then get forwarded to me Exchange 2003 server.  The issue is that I have application servers at hospitals that will not allow my bmail program to send out on port 25.  Instead I have them setup to send to my server using port 2525. This all worked fine on Exhange 2003 as I had my server setup to rceive emails on port 2525 as I had a spam software product using port 25.

Now emails are being routed to my exchange 2010 server and smpt service is setup on port 25 like the default.  All mail that is destined to come to me on port 2525 is not getting to my new exchange server.  I have setup a new receive connector on port 2525 but it is not working.  Do I have to do something with the SMTP service as well?

coming back to my question above, did you check the firewall of the exchange 2010 server?normaly you don't need to do any further changes to be able to connect to the port with telnet.they only thing you need to do afterwards is to set the permissions for anoymous as mentioned above.

the settings you need to check are
Bindings = {0.0.0.0:2525}
PermissionGroups = AnonymouseUsers,Custom
RemoteIPRanges = {10.0.0.0/24}

the RemoteIPRanges should be the subnets/IP addresses that will use this connector

can you temporarily disable the firewall on this exchange server to ensure that it is not the issue? then attempt to telnet from your workstation on port 2525

that means the connector is working and something in front of your exchange server is blocking the port
