Hi Everyone,

Is this behaviour a bug in RT or misconfiguration?

* Create a RT-User foo at example.com, foo at example.com doesn't exist in our Exchange-Server,
* Create a Ticket with foo at example.com as Cc
* Reply to this ticket
* Exchange replies that foo at example.com doesn't exist
* RT distributes this mail to all Ccs, etc. of the ticket, excluding foo at example.com 

-= (At this point we notice the User with the invalid e-mail-address and try to resolve this error) =-

* Merge RT-User foo at example.com into the RT-User bar at example.com, ( bar at example.com exists in our Exchange-Server. )
* Reply to this ticket
* Exchange replies that foo at example.com doesn't exist
* RT distributes this mail to all Ccs, etc. of the ticket, including foo at example.com
* Exchange replies that foo at example.com doesn't exist
* Repeat ad infinitum 

We broke this loop by taking RT offline, deleting all errormails from the mailq and setting the EmailAddress-Attribute of foo at example.com to bar at example.com in the database.

Cheers,
Vinzenz
