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 listed in the Source Server
However, occasional e-mails are going out via server 2
They are getting bounced because we dont; have reverse dns and other things set up for it
Why are some e-mails going out via Server 2 ?
Thanks,
Steve
- 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!

Shadow redundancy in Exchange Server
https://learn.microsoft.com/en-us/exchange/mail-flow/transport-high-availability/shadow-redundancy?view=exchserver-2019/?WT.mc_id=M365-MVP-5002523- 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
