Here is just a short list of tickets related to this single exim alias:
T82660 , T109396, T170361, T150463, T124449, T103029, T132230, T84507, T84696, T81249 , .. ,...
per parent task and all the other "sister" tickets, move this away from Operations and over to the control of OIT in Google please
That way Office IT could directly control this alias and make the needed changes and doesn't have to create tickets for Ops anymore.
