Autocreated users, howto disable this


I know this has been asked before but not real solution was given.

I would really like only registered users to be able to use our RT
system. But sometimes odd emails hit the rt address and then a new user
is created for that email address.
This is really irritating and I would like to disable this autocreate
feature. The best scenario would be if rt replies with instructions on
how to contact someone etc.

Thanks in advance
