Receiving emails from unwanted sources
As a test I have set up firstname.lastname@example.org as the Default System Email, I then notice several new tickets created from unrelated emails from mydomain.com, I then created an email filter to blockemails from mydomain.com as I only want to receive tickets externally, but now it's creating tickets from external sources aimed at email@example.com.
I can't figure out why this is happening as I was expecting only creation of new tickets when emails sent to firstname.lastname@example.org
Am I missing something?
