How about a way to reject messages if there is anyone but the various registered service desk email addresses in the to or cc field?
Team,
We try to instruct our users to stop cc'ing people on tickets, but it's a tough sell...
I'd love to be able to reject service requests if they have more than one recipient (that recipient being one of my registered service desk emails) AND I'd like to have an auto-generated message explaining, using my preferred wording, that the email has been rejected.
This would really make the product stand out from your competitors.
