Hi Pete, thanks for the very good and informative reply!
I have made the change as you suggested, and yes it does work on my side,
and yes, it did trap the mail without any problems. I am still not sure why
the original e-mail got through though.
I am aware that we could have legitimate e-mails that are caught by this
recipe, hence them being archived in an audit folder. We have someone who
goes through the folder 2 daily to forward on the legitimate stuff (so far
we have not had many).
Regards
Enrico
