Mail being Sent out via Server with no Send Connector configured
Exchange 2019 on prem - fully patched in a 2 Server DAG config Only server 1 is configured to send out e-mails via the Send Connector ie - in Scoping of the Send Connector, only server 1 is list...
In the case of Exchange DAG, Safetynet is activated by default, so mail is stored on both servers.
Therefore, if mail is not stored on both servers, mail is not sent.
To prevent delays in processing this part, try setting the safetynet function to off!
Set-transportconfig –ShadowRedundancyEnabled $false

I've had a look at this article and other linked articles
They don';t seem to indicate why a Send Connector that's only configured for 1 server would be used by anther server
