I've gone through as many of the help forums I could find and settings relating to the escalation email notifications but seem to be a bit stuck on this one.
Just set up a new system (we were previously using version 3.1) but built a new v.6 Patch 4 which is all up and running and working fine - however, we do have escalation / sla rules in place to push certain tickets into the escalation queue, but this is also generating escalation event notification emails and sending it to all agents within otrs, which we want to disable.

However, even with these event notifications disabled in the settings we still seem to have the emails coming through.

Any suggestions would be greatly appreciated
