That will obey the filter file for *every* message; I take it that is
what you want.

That will save a copy of all messages in /tmp/system-mail-filter.out,
and pass some to your script. Ah! Perhaps that's your problem. Should
that really be "unseen save"? Messages that are to domains other than
those you test for will just get saved there and not passed on to
anything else.

I don't know tcl, but the script doesn't seem to be resubmitting the
message anywhere... Have I missed where it is directing the output back
to Exim?
