    I'm not buying it. I think there is a more obvious cause here. Spammers
    spreading their load out across multiple relays. I spoke with the
    original complainer and was able to correlate her problem with our
    current problem. Sure our load was lighter but we were able to trace the
    problem back to to subnets. 64.119.220.0/24 and 64.119.213.0/24. Both
    netblocks are allocated to the same company.
