Title
Can CMN Mail Connectorlisten from 2 different ports? -
Description
You may need CMN Mail Connector to listen from ports 25 and 26.
The reason behind is because email leaves from Domino Server via port 26, so CMN has to listen via port 26. Then, Office365 Outbound connector delivers mails over port 25, so CMN will also need to listen via port 25.
-
Cause
CMN Mail Connector is designed to listen from one Inbound port.
-
Resolution
WORKAROUND
Setup two CMN Mail Connector consoles; one for each Inbound port.
