[rt-users] Users and recipients

[Mauricio Tavares]

	I am trying to understand a bit more how RT works, so I do apologize in 
advance for the trivial questions:

  1) When someone sends a support email to RT, it first sees if the users
exists on the databases it uses to do user authentication. The local 
database is checked last even if it is not explicitly defined. So, if we 
are doing LDAP authentication, RT will first look up the user there and 
then go to the internal database.

  Q: What does it use to uniquely identify a user? It seems that it will 
look up the username to compare with users already defined. What else?

If the user does not exist -- customer sending a ticket for the first
time -- RT will create that user (in groups Everyone and Unpriviledged)
and associate the ticket to the user.

  Q: If I send a test ticket to RT, using the email address
raub at testdomain.com, it does not send the ticket back to that address.
In the ticket data screen, it correctly identify Requestors as
raub at testdomain.com. But, it seems when it process the email, it does
not seem to know the recipient = raub at testdomain.com. Even if I access
the ticket (as in log in with my normal/LDAP-based/part-of-support-group
account) and try to reply to it by selecting raub at testdomain.com as the
email to send the reply to, it still seems not to find the recipient:

How come?
