I don't see how you can have a false positive on an open relay test. Either
it allows you to send a test email through, or it doesn't. If it does,
it is by definition open.
Unless you mistakenly test a site that considers you to be a customer
and has specifically allowed relaying for you. But for somebody to
do that for ORBS, say, would be like calling them up and leaving a
voicemail saying "please block me, I dare you."
