+ DESCRIPTION:
+    Citadel does not retry SMTP delivery at a fixed interval.  Instead, it
+starts at a nominal interval (15 minutes by default) and then doubles the
+interval after each failed attempt.  This instruction contains the interval
+which should currently be followed (and doubled again, if the next delivery
+fails).
