I'd suggest that "mild inconvenience for you" is not a synonym for
"too many false positives."  I've been running IPv6 on my server for
quite a while via a tunnel from HE, which includes the ability to
manage my own reverse DNS.  (Thanks!)  When I look at the logs, I see
precious few inbound connections with no rDNS that plausibly could be
anything other than a spambot or yet another compromised web host.

Every mail system in the world is reachable via IPv4 and will be for a
long time.  If your v6 setup isn't ready for prime time, it really isn't
anyone else's job to help you experiment.

R's,
John
