I applied the patch the other day using the debian package of ytnef

Tested it a bit and it seemed fine but all sorts of things went
awry the next day - attachments went missing, and/or turned up on
the wrong email messages! I was totally confused as to what might
be going on until one user rang me and said the person sitting next
to her sent her an email and it collected someone else's attachment
on the way. Ooops, said i, and rapidly put back the backup of
mimedefang-filter.
Upon further reflection i think my problem might be the line
calling ytnef - perhaps stupidly i just altered the path, but
didn't think about the calling parameters so it says
@new_files = `/usr/bin/ytnef -f Work $path`;
now if i'm reading ytnef help output correctly, i think that should be
@new_files = `/usr/bin/ytnef -f . $path`;
can someone confirm/deny this for me before i go and mess things up
again? :)
to answer my own question - i tested the second version on the
weekend and it all seemed to work fine. Now come monday morning and
people are reporting phantom attachments again (four 0-byte PDFs in
the last one reported) Is it that the attachments are being processed
in the same directory and under load some messages are being
processed at the same time as each other out of the same directory?
That's about the only explanation i can think of for the behaviour
i'm seeing - although now i think of it, doesn't MD create a temp dir
under /var/spool/MIMEDefang for each message it's processing?
Also i'm wondering about the '-f Work $path' of the original line as
'Work' doesn't seem to be a perl variable or a parameter that (my
version of) ytnef seems to know about.
well anyway being a non-perl guru i've put my md-filter up at http://
www.f8.com.au/mimedefang-filter in hope someone can have a look at it
and tell me what i've done wrong? appreciated..
..S.
PS fwiw it's debian testing/unstable kernel 2.4.30 running the dpkgs
of mimedefang 2.51-2; perl 5.8.4-3; sendmail 8.13.1-16; ytnef 2.6-1...
