+## 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.
