[rt-users] 3.4.4 --> 4.0.4 and subject tag

[Jeff Blaine]

Right now, with $rtname set to "ATCC" and a test
queue configured to have its own subject tag ("DEMO"),
our autoreply is showing signs of split-personality
disorder:

==============================================================
Subject: [DEMO #35372] my X is broken
...
There is no need to reply to this message right now.  Your
ticket has been assigned an ID of [ATCC #35372].

Please include the string:

          [ATCC #35372]

in the subject line of all future correspondence about this
issue. To do so, you may reply to this message.

==============================================================

Is this because, perhaps, our old 3.4.4 template was brought
into RT 4.0.4 when we upgraded, and it uses $rtname and not
something new to reflect the subject tag?  If so, what is
that?
