from what I can tell, RT does not use the “Errors-To” header for the mail it generates. Yesterday, a mail bounce problem for a queue watcher caused thousands of tickets to be auto-created in our installation. There is a huge dollop of blame for our not filtering out bounce messages or using existing bounce processing mechanism(s) in RT. But if RT added an Errors-To header (pointing to a non-auto-ticket-creating address), this sort of thing would not happen. What am I missing? (I must be, since otherwise the feature would exist by now).
