## Original script adapted from source: http://wiki.mutt.org/?ConfigTricks/CheckAttach
##
## Adapted by Ismaël Bouya (http://www.normalesup.org/~bouya/) to make it so
## that retrying to send the email shortly after will work
##
## Edit muttrc to have this line:
## set sendmail = "/usr/local/bin/mutt_check_attachment_before_send.sh /usr/lib/sendmail -oem -oi"
##


## Attachment keywords that the message body will be searched for:
KEYWORDS='attach|joint|voici|voil'

## Check that sendmail or other program is supplied as first argument.
if [ ! -x "$1" ]; then
    echo "Usage: $0 </path/to/mailprog> <args> ..."
    echo "e.g.: $0 /usr/sbin/sendmail -oem -oi"
    exit 2
fi

## Save msg in file to re-use it for multiple tests.
TMPFILE=`mktemp -t mutt_checkattach.XXXXXX` || exit 2
cat > "$TMPFILE"

## Define test for multipart message.
function multipart {
#    grep -q '^Content-Type: multipart' "$TMPFILE"
    grep -q '^Content-Disposition: attachment' "$TMPFILE"
}

## Define test for keyword search.
function word-attach {
    grep -v '^>' "$TMPFILE" | grep -E -i -q "$KEYWORDS"
}

## Header override.
function header-override {
    grep -i -E "^X-attached: *none *$" "$TMPFILE"
}

function ask {
	terminal=`tty`
	dialog --yesno "Envoyer malgré la pièce jointe manquante ?" 5 30 < $terminal > $terminal

#Verifie qu'on a essayé de l'envoyer y'a moins d'une minute

	return 0
	fi

## FINAL DECISION:

## That's all folks.
