[rt-users] RT not setting return email address

[David]

Greetings all,

I have rt installed (3.0.11) and working but it doesn't set the reply-to 
address properly.  The address is set in the queue properties but when I 
click reply it replies to the email address located on the individual 
server.

    eg: rt at host.domain.com instead of rt at domain.com

I have read that the you can change the headers via the templates but I 
cannot for the life of me figure out what module/routine to use.

TIA.

David.
