[rt-users] how to filter SPAM

[carles at inlander.es]

We receive a lot of SPAM in the RT account. When we receive it, RT
creates a ticket on it and sends the autorespond template. We don't want
to do that.

Can RT filter the incoming mails by the subject or similar? For example,
we can request our customers to put a string in the subject, and RT
discard all the mails that doesn't have this string (like when the
ticket is opened).

I know that this can be done by procmail or any similar program, but is
it possible to do by RT?

Thanks a lot
