Re: pipe and resend mail

Stéphane MERLE Fri, 23 Dec 2016 03:34:57 -0800

not good:

3 phases :


1 --> the mail is for admin or CRM ? --> forward to admin or crm && return 0

2 --> the mail is crap --> delete it && return 0

3 --> none of the previous --> send to bdd by api rest call http

so the sendmail is not always the final decision ...

I feel that the originale recipient is kept so the mail is looping ...


for now, my code is as follow :


#!/bin/bash
#
LOGFILE=/var/log/filter_dyn_v2.log
touch $LOGFILE
exec >> $LOGFILE
exec 2>&1

echo "Parametres : $@"

# je bascule le message dans le descripteur 3
msg=$(mktemp /tmp/msg.XXXXXX) || exit 75
cat > $msg || { rm $msg; exit 75; }
exec 3< $msg || { rm $msg; exit 75; }
rm $msg

# je traite les paramètres de l'appel
sender=${1:-}
shift
recipient=${1:-}
shift
queue_id=${1:-$RANDOM}
shift

CRM="contact_a...@mondomaine.com"
ADMIN="stephane.me...@mondomaine.com"
API_PATH="http://api.mondomaine.com/api/V1.0/add_mail";

atraiter()
{
        echo "[$queue_id] appel api"
        perl -e 'open IN, "<&", 3; seek(IN, 0, 0);'

        lemail=$(cat <&3)

        lefrom=$( echo "$lemail" | grep -E "^From:.*" )
        leto=$( echo "$lemail" | grep -E "^To:.*" )
        lesujet=$( echo "$lemail" | grep -E "^Subject:.*" )
        lereplyto=$( echo "$lemail" | grep -E "^Reply-To:.*" )

echo "curl -s -X POST -F \"queue_id=$queue_id\" -F\"sujet=$lesujet\" -F \"mailfrom=$lefrom\" -F \"mailto=$leto\" -F\"replyto=$lereplyto\" -F \"body=lemail\" \"$API_PATH\""curl -s -X POST -F "queue_id=$queue_id" -F "sujet=$lesujet" -F"mailfrom=$lefrom" -F "mailto=$leto" -F "replyto=$lereplyto" -F"body=$lemail" "$API_PATH"

        if [ "0" -ne "$?" ]
        then
            echo "[$queue_id] ERREUR CURL : $?"
            return 75
        fi
        echo
        echo "[$queue_id] CURL OK"
        return 0
}

renvoi()
{
        # renvoi du mail a un destinataire
        local destinataire=$1
        echo "[$queue_id] j'envoi le mail a $destinataire"

        perl -e 'open IN, "<&", 3; seek(IN, 0, 0);'
        set -- "$@" "$additional_recipient"
        exec /usr/sbin/sendmail -vv -i "$@" <&3
        return $?
}

now=$(date +"%m/%d/%Y")
timenow=$(date +"%Hh%Mm%Ss")
echo "[$queue_id] $now $timenow"

perl -e 'open IN, "<&", 3; seek(IN, 0, 0);'

if grep -Ei "(operation numero|indice defrequence|signaletique|stephane@domaine)" <& 3 >/dev/null; then

    renvoi $CRM
    exit $?
fi

perl -e 'open IN, "<&", 3; seek(IN, 0, 0);'
if grep -Ei "(assistance admin|help admin)" <& 3 >/dev/null; then
    renvoi $ADMIN
    exit $?
fi

#trash
perl -e 'open IN, "<&", 3; seek(IN, 0, 0);'

if grep -Ei "(demande rejet|application refusee|Content-Type:application\/zip)" <& 3 >/dev/null; then

    echo "[$queue_id] $now $timenow non pris en compte, je trash"
    exit 0
fi

# j'enregistre tout le reste dans la base
atraiter
exit $?

a lot simplier than before, but still I feel to make it bad with my :lemail=$(cat <&3) but the easiest way to get the content for the API.

And do not forget the '--' in
pipe ... argv=/path/to/script -f ${sender} -- ${recipient}

And the missing "< $msg" in the final command:

        /usr/sbin/sendmail "$@" < $msg
