Bug#223593: #223593: Whitelisting with EoC

Version: 1.2.6-1

With the --post option it is fairly simple to create moderation
whitelists by using a pre-EoC filter.  I just built a moderation
whitelisting system for a EoC mailing list as follows:

First, note that I am using Postfix and a separate lists domain here.
All mail to foo@... gets sent to
jyvilists-foo on
the server.  I'm using Maildrop as the MDA and its filter language to
preprocess EoC mail as follows:

import SENDER
import LOCAL
import RECIPIENT

IGNORE=`enemies-of-carlotta --is-list --skip-prefix=jyvilists-
--domain=lists.jyvaskylanvihreat.fi --name $LOCAL`
if ($RETURNCODE != 0)
{
        echo "no such address $RECIPIENT ($LOCAL)"
        EXITCODE=67
        exit
}
EOC_OPT=''
if ($LOCAL eq 'jyvilists-ehdokkaat' && lookup($SENDER,'ehdokkaat-whitelist') )
{
        EOC_OPT='--post'
}
to "|enemies-of-carlotta --skip-prefix=jyvilists- --domain=lists.jyvaskylanvihreat.fi $EOC_OPT --incoming"
