In my sample code, I did just that; albeit on the condition

I can confirm this works (at least on my system). Piping only
the body and removing the --mbox option still scans correctly.
This is maddening. Now I can't get it to work with 'w' at all. Here's what I'm
running:
# uname -a
Linux server.ttlexceeded.com 2.4.20-686-smp #1 SMP Mon Jan 13 23:06:41 EST 2003
i686 GNU/Linux
# procmail -v
procmail v3.22 2001/09/10
[...]
# spamassassin -V
SpamAssassin version 2.63
With VERBOSE=on, I see: Program failure (1) of "clamscan" when using that line
(including variations of adding the full path to clamscan).
When I use:
:0 wib
VIRUS=|/usr/bin/clamscan -i --disable-summary --stdout -
or
:0 wib
VIRUS=|/usr/bin/clamscan -i --disable-summary --stdout -
I get procmail: Skipped "Worm.Gibe.F FOUND" (or similar) messages from
clamscan/clamdscan. Clearly I'm doing something silly with procmai, and it's
interpreting the result a path (?)
With:
:0 wib
VIRUS=`/usr/bin/clamscan -i --disable-summary --stdout -`
I get results like:
From XXX Fri Feb 13 13:08:58 2004
Subject: RE: OPST vs CEH
Folder: VIRUS=
If found that:
:0
VIRUS=|/usr/bin/clamdscan --mbox --disable-summary --stdout -
or just:
VIRUS=`/usr/bin/clamscan -i --disable-summary --stdout -`
work. I'm happy, but I do want to understand what I'm doing wrong. Is there a
major adantage or disadvantage to either of these? Why won't the w (with or
without i,b) work consistently?
I don't want to beat this to death, but I'm trying to figure out why my results
seem to vary so much from what "should" work with procmail.
Lest Dallman and others think I'm ignore your excellent suggestions for
optimizing procmail performance, I'm deliberately taking a path that might not
be as efficient, but that provides some extra logging for gathering stats, etc.
This, I'd ideally have a header which indicates whether or not a virus is
detected.
Thanks,
