Hi Greybeard,
On page

Email Options-
silent=1 - Skips sending email notifications to all operators
supervisor=oper1 - Set an operator as a supervisor and Cc: this operator in addition to operator on Ticket (It's been reported that using this feature blocks emails from going to the assigned Operator.)
Might be a good start point ....
Have a good one !
