Just consider someone, a customer of yours maybe, forward a message
titled "Re: [Ticket #4712] not a bug" to your RT, which you confi-
gured with $rtname "Ticket".
That message would be either incorporated in your RT's ticket number
4712 or rejected because you're not yet have 4712 tickets.
Either way, it's not what should happen and your customer might be-
come rather confused if something like that actually would happen.

This might seem constructed at first sight, but this possibility quite
exists, at least with generics like "ticket", "bug", "request" ... By
using your domain name, one could easily even have two RTs talk to
each other ;)

I know of two ISPs unsig RT for at least some part of their communication.
Both do use their FQDN as their $rtname as well, so forwarding messages
from one ISP to the other does not break anything.

Consider my example above, using generics like "Ticket", you quite pos-
sibly might get in that kind of trouble. What's wrong with "[TerraLuna.Org #1]"?
