There's still another possibility:
1) Change your qmail-send run file to deliver to a script:
exec env - PATH="/var/qmail/bin:$PATH" /var/qmail/bin/qmail-start \
"| /usr/local/bin/virus_scanner"
2) Create a /usr/local/bin/virus_scanner, it should read the mail
from stdin and deliver (or refuse) the mail depending on scan results.
I use this scheme for tagging spam with SpamAssassin, modify to your needs:
==============8<========================================================
#!/bin/sh
SPAMC="/usr/bin/spamc"
DISABLED_FILE="/var/qmail/control/DISABLE_SPAMC"
LOGGER="/usr/bin/logger"
SPAMD_HOST="127.0.0.1"
CONFFILE="/var/qmail/control/spamc_conf"
# deliverquota from courier package
DELIVER_PROGRAM="/usr/bin/deliverquota -c"
do_log() {
$LOGGER -i -p mail.info -t SPAMC_WRAPPER $1
}
[ -f $CONFFILE ] && . $CONFFILE
if [ -f $DISABLED_FILE ]; then
do_log "spam tagging disabled (found $DISABLED_FILE), \
running $DELIVER_PROGRAM"
$DELIVER_PROGRAM "$HOME/Maildir" "$MAILDIRQUOTA"
else
do_log "spam tagging enabled, running $SPAMC and $DELIVER_PROGRAM"
TMPFILE=`tempfile -p SPAMC`
# I use create&unlink here, so the stdin for DELIVER_PROGRAM is
# seek()'able
$SPAMC -u $USER -d $SPAMD_HOST > "$TMPFILE"
exec 4< "$TMPFILE"
rm "$TMPFILE"
exec $DELIVER_PROGRAM "$HOME/Maildir" "$MAILDIRQUOTA" <&4
