[rt-users] prevent auto-response for some senders?

[Les Mikesell]

I've given out the helpdesk email address to
several outside entities for notification of
planned outages and similar events.  Now that
I'm letting RT handle the address I'm probably
bothering people that don't want to get a ticket
number.  Is there any way after a new user entry
is auto-created from the first email to specify that
subsequent mail from that address should not generate
any response back to the sender?
