set mail_interval [<seconds>]
This setting controls how often the client checks your mbox for new mail. The default value is 60 (at the top of every minute).
Previously, this value was not configurable and the client would just check for new mail at the top of every minute. For some people, this was far too often, and for others, it was not nearly often enough. Now you can control exactly how often your mbox is checked with this /SET. Please remember that redrawing your status bar no longer rechecks your mail; what you see on your status bar is cached and recreated by a recurring timer that runs as often as this /SET directs.
When CPU_SAVER mode is active, /SET CPU_SAVER_EVERY will override this value.
