    I outlined my experience with this in August in a thread titled "Poor
    Man's Greylisting". I've been doing it for over a year, with no false
    positives that wouldn't have been rejected by other means. The best
    thing is that it reduces the load on Postfix, which never sees the
    messages. It's also an effective solution to direct-to-MX spam, if you
    don't require a real backup MX.

    If anyone else has tried out this technique, I'd be interested to hear
    of the results, especially on large sites.
