Change SMTP port on Exchange Send Connector
Posted on 2016-11-22
I can't seem to do anything outbound on port 25 from a certain client site. The ISP says they are not blocking the port. I've tried 2 different routers and the same issue exists.
Exchange 2010 is currently configured to send via Smart Host or port 25.
If I can get the Smart Host provider to reconfigure to listen on 587, can I just modify the Exchange Send Connector default port?
Set-SendConnector “ConnectorName” -port 587
Any issues with doing so?
