Change port used by Exchange 2007 or 2010 send connector when using smarthost
Posted by shauncroucher on February 16, 2010
A lot of people are having trouble finding where they can change the port used to send outbound mail to their smarthost provider.
Some smarthost providers will only allow you to connect to ports other than port 25. Godaddy are a good example of this, where the relay service they offer their customers typically operates on port 3535
The bottom line is that you have to configure the port used by a send connector at the Exchange Managment Shell. It cannot be done using the Exchange Management Console.
It’s easy enough.
To find the ports used by all your send connectors along with the smarthost used just open the shell and type:
Get-SendConnector | ft Id*,Sm*s,po*
Now, to send the port to something different just run Set-Sendconnector. So if the connector is called “OutboundMail” and you want it to use port 3535 it would be:
Set-SendConnector “OutboundMail” -port 3535
