[Exim] unseen system filter - bypassing particular user

Hi all,

running exim 3.35 on Debian woody.

I have a system filter to catch a copy of all email in and out of the box
with

enseen deliver user@???

this works well.

My boss has asked me to ensure non of his or the 2IC's mails go through
the filter.

Have tried with

if $header_From: contains "boss@???"
or $header_To: contains "boss@???"
then save /home/boss/Maildir/folder/
unseen deliver user@???
endif

but then exim gives me an error about message_filter_directory_transport
being required in the exim.conf.

I put this option in the config and test with exim -bV (no errors) but
still get filter errors in the log relating to the
message_filter_directory_transport problem.

There doesn't seem to be much about the issue when Googling leading me to
think I am doing something wrong somewhere obvious to everyone except me
:)

1. Is this the right way to tackle my problem?
2. Any suggestions?

thanks

-Matt
