Yes - that gives the "AND" logic that's asked for.

As for the XBL, we've used it for years and have only ever had to
whitelist a tiny number of IPs that we wanted to hear from, despite the
(most likely correct) listing. Then again, we _could_ have considered our
security policy and decided that it would be unsafe to accept ANY email
traffic from a compromised system, until it's properly cleaned.

Also note that many very large ISPs use XBL too, so anyone with a legit
server that gets hacked and listed will experience a HUGE amount of pain
- it won't just be you they can't mail...
