+# mutt/sendmail – sendmail wrapper to enforce some checks on outgoing mails
+#
+# The script basically just creates a temporary file and then invokes any
+# executable scripts in ~/.mutt/sendmail-checks.d in run-parts style. They
+# receive the filename of a temporary file holding the message to be sent as
+# $1, followed by all recipients as determined by mutt.
