- Our outbound service requires TLS encryption (using STARTTLS). We have seen evidence that some versions of Exchange do not use TLS by default on port 25. To correct this, switch the port on your outbound connector to either 587 or 465 as follows:
1- Open the "Exchange Management Shell"
2- Get the identity of the outbound send connector by running:
3- Then, once you have the identity, you can change the port by this command (replace "SpamHero SmartHost" with the correct identity):
Set-SendConnector -identity "SpamHero SmartHost" -Port:587
4 - If your domain has an SPF record, see: How to include SpamHero's IP in your SPF record.
