[Esd-l] Qmail+Sanitizer

[bobk at dwcinet.com]

I currently am trying to implement the sanitizer on a
qmail+vpopmail+qmailadmin+sqwebmail test mailserver.

I keep running into some problems.
When I test the server by emailing it a poisoned executable I get this in
my procmail.log

Sanitizing MIME attachment headers in "test" from <bobk at dwcinet.com> to
vpopmail

I am having problems finding somewhere to put quarantine as well as some
other bugs.

Here is what my procmailrc looks like.

PATH="/usr/bin:$PATH:/usr/local/bin:/var/qmail/bin"
SHELL=/bin/sh

POISONED_EXECUTABLES="/etc/procmail/poisoned-files"
SECURITY_NOTIFY="root at qmail.dwcinet.com"
SECURITY_NOTIFY_VERBOSE="root at qmail.dwcinet.com"
SECURITY_NOTIFY_SENDER="/etc/procmail/policy.note"
SECRET="sdflksjas"

ORGMAIL=
MAILDIR=$HOME/Maildir
DEFAULT=$MAILDIR/
SECURITY_TRUST_HTML=N
DEFANG_WEBBUGS=NO
SECURITY_QUARANTINE=/var/quarantine
POISONED_SCORE=135
SCORE_HISTORY="/var/log/macro-scanner-scores"
SCORE_DETAILS=YES
DROPPRIVS=YES
LOGFILE=/var/log/procmail.log

:0

       * ^To:.*
       {
           MANGLE_EXTENSIONS='exe|com|cmd|bat|pif|sc[rt]|dll|ocx|dot|xl[wt]|vb[$
       }

# Finished setting up, now run the sanitizer...
INCLUDERC=/etc/procmail/html-trap.procmail
# Reset some things to avoid leaking info to
# the users...
POISONED_EXECUTABLES=
SECURITY_NOTIFY=
SECURITY_NOTIFY_VERBOSE=
SECURITY_NOTIFY_SENDER=
SECURITY_QUARANTINE=
SECRET=

If someone would be so kind as to enlighten me as to what I am doing
wrong. I have run the sanitizer for over a year on multiple sendmail
servers but never tried it on qmail till now.
