SCRIP - User defined condition


after reading the docs and wiki (and didn’t know perl) i didn’t could solve my problem.

I need a “User-defined-condition” on a SCRIP:

The “on-correspond-scrip” should NOT execute

if the email comes from ""
and the subject contains “Your Call is”

Background: an external hotline (which is in the Cc-List) gets his own mails back … they are playing “ping-pong”

Who can help me with some code?

Thank you
