    We have been using the Spamhaus ZEN now for some years, never any big problems with false positives, even though the ZEN is supposed to be pretty strict. Over the years I had to manually whitelist two IPs, but that's all.

    Some other related questions:
    - What are your setting for SPAMassasin for this client?
    - Do you use Greylisting? (Reduced the SPAM a lot for us)
