Antispamcloud / Spamexperts default settings change port to 587 / 550 Mail-relay not allowed

So yeah, I just updated my smarthost settings for my send-connector, and ofcourse, I forgot to change the port to 587. You can't do this for Exchange in the adminwebpanel nor in the settings-gui. No you can only do this as an administrator in powershell with the exchange add-in enabled or invoked. The code you need to run is:

Set-SendConnector -identity "NAME OF CONNECTOR" -Port:587

Don't remember your connector name? Look it up with:

Get-SendConnector | fl
