block sender + use with maildrop

Dear All ,

Right now I can use the block_sender  plugin only with procmail,but if
 a slight modification on php code, we can use the same plugin for
maildrop also.

This is the only change to use block_sender  pluging to use with
maildrop (copy this sample  maildroprc to /etc/maildroprc ), I take
this code from spamrule plugin and modified it.

[root@gejo block_sender]# cat /etc/maildroprc
##
# /usr/local/etc/maildroprc:  global maildrop config file
#
# See maildropfilter(5) and http://www.flounder.net/~mrsam/maildrop/
# for more info.
#
# $Id: maildroprc,v 1.10 2003/07/01 07:40:24 root Exp root $
##
DEFAULT="$HOME/Maildir"
logfile "/var/log/maildroprc.log"
MAILDIR="$DEFAULT"
FILTER="/var/local/squirrelmail/data"
FILTERS="$FILTER/$LOGNAME.maildropblock"
VERBOSE 9
# where to deliver mail by default


# where to send junk mail
JUNK="$MAILDIR/.Junk"
TRASH="$MAILDIR/.Trash"

# junk filter tag
JUNK_TAG="X-Spamrule"

# virus filter tag
VIRUS_TAG="X-Antivirus"

# where to send virus-infected mail
VIRUS_BOX="/usr/mail/quarantine"

# sitewide filter tag
SITEWIDE_TAG="X-Global-filter"

# what shell to use for system commands
SHELL=/bin/sh

# The exit code that will tell qmail-local to stop processing a user's
# .qmail and don't try delivering the given message any more:
#    99 = tell qmail that the message was delivered successfully (blackhole it)
#   100 = tell qmail that the delivery failed permanently (reject it)
# (See qmail-command(8) for more info.)
EXIT_BLACKHOLE=99
EXIT_REJECT=100

# Immediately deliver mail from system accounts to the user's mailbox,
# bypassing any filters they may have
# (This looks a lot like the always-allow rule)
exception {
    import SENDER
    SHELL=/bin/sh
        BLOCKED=$FILTERS
    # is the envelope sender in the allowed senders list?
    if (lookup($SENDER, "$BLOCKED"))
    {
        xfilter "reformail -A '$JUNK_TAG: allowed: sender \"$SENDER\"
overrides filters'"
        to $TRASH
    }

    # what about the header sender?
    /^From: .*/
    foreach (getaddr $MATCH) =~ /.+/
    {
        if (lookup($MATCH, "$BLOCKED"))
        {
          xfilter "reformail -A '$JUNK_TAG: allowed: sender \"$MATCH\"
overrides filters'"
          to $TRASH
        }
    }
}

This is the area which needs php  code  modifications .Right now I am
creating this file by using sed command .if modify  our code to change
[email protected] to ^gejo@bos\.test\.co\.in$ .  and save the output
 on $LOGNAME.maildropblock  .,so that all the users can enjoy by use
the same code for maildrop filtering also.The output contains two
files $logname.block and $logname.maildropblock

[root@gejo block_sender]# cat
/var/local/squirrelmail/data/[email protected]
^gejo@bos\.test\.co\.in$
^billing@aloha\.net$
^feedback@aloha\.net$

[root@gejo block_sender]# cat /var/local/squirrelmail/data/[email protected].
[email protected]
[email protected]
[email protected]

I tested the same and it is working fine

Regards
Gejo
