[rt-devel] Hiding Tickets (in email messages)

[mixo]

Is there a way of setting up RT 2 to send mail (correspondece) messages
without actually sending the Ticket itself. My problem is, if I send
mail to RT 
which has an attachment, the attachments (i.e not "content-type :
text/plain ")
can be viewed without RT. How can I prevent this? I want users to ALWAYS
login
to see tickets, even though they are watchers.

Thanks
