I checked the log on the relay and it seems only some of the email is going through.
I suspect based on the behavior I was seeing that the alerts to agents may be using the email tab and not the 365 tab settings?
So the next question is could your solution of using the local MTA instead be changed to use the relay I have configured on my other server?
Or I suppose I could have the local MTA forward to my relay server as well.
Also, are there any kind of issues with using the config you mentioned?
I’m thinking about something like settings being reverted on updates.
Or anything else you have encountered after beginning to use the local MTA.
Thanks
