+Look for mail older than the time of the last successful query.
+Using a small interval will reduce bandwidth use. A larger
+interval reduces the likelyhood of missing a result due to MTA
+delays or downtime.
+
+The time(s) of the last successful queries are the C<lastresult>
+values visible from L<lei-edit-search(1)>.
+
+Date formats understood by L<git-rev-parse(1)> may be used.
+e.g C<1.hour> or C<3.days>

+Default: 2.days
