we just realized that the autoreply on ticket creation did not work for
one of our queues.
The reason was that $Ticket->QueueObj->Tag was used in the template
which made it fail silently. This is very likely related to the moving
of the Branded Queue Module into core.
While the reason was readily apparent when looking into the log files,
silentely failing is, imo, not an option. RT should, again imo, send
email to rtmaster informing him/her of the situation and should log the
failure with the ticket. This could be important in case there is an
argument over who sent what at what time.
Thanks yet again,
