This extension for RT 3.2 and 3.4 allows sites to "Brand" individual queues with distinct tokens in the Subject: headers of outgoing email messages. To enable this extension: # cd into the unpacked distribution directory perl Makefile.PL make make install # edit your RT_SiteConfig.pm library to add the following line # immediately before the last line of the file: use RT::Extension::BrandedQueues; # The only thing after that use ..." line should be the line: 1; You'll also need to modify any of your local email templates which use the $rtname variable. To edit your templates, log into RT as your administrative user, then click: Configuration -> Global -> Templates -> For example, RT's default "Autoreply" includes this line: "There is no need to reply to this message right now. Your ticket has been assigned an ID of [{$rtname} #{$Ticket->id()}]." Change this line to read: "There is no need to reply to this message right now. Your ticket has been assigned an ID of [{$Ticket->QueueObj->Tag} #{$Ticket->id()}]."
