Can your single user see those tickets in the RT web interface? This
ensures that the rights are configured correctly.
It's possible that RT might not be sending mail because it identifies that
user as the user creating the ticket, and by default, RT doesn't email a
user about their own actions.
I have a fresh installation. I created several queues, and a single
user, and added that user as the AdminCC to the queues. RT ships with
a scrip called "On Create Notify Owner and AdminCcs" which is enabled
and left to the default settings. I set up a few aliases from
addresses like supp...@kath
