Personally, instead of using 'logrotate' I configure syslog-ng to
name the 'destination' file as the hour of day and day of week,
and let it automatically create new files on the hour.

For example:
     file("/var/log/mail/$WEEKDAY/$HOUR" remove_if_older(172800) );

If you only need today's log messages on hand, you could do:
     file("/var/log/mail/$HOUR" remove_if_older(7200) );
