I'm currently evaluating my options to best automate some of the
findings that I've got so far (I didn't ask for a common format for
replies, so most will be manual).
However, an interesting item that I've noted thus far, is that ~50% of
all successful connections do not have rDNS.
Originally, I thought that the majority of these simply didn't have
their delegated reverse zones on v6-reachable DNS servers, but this is
not necessarily so.
I copied the web log onto a dual-stack box and re-ran the DNS tests, and
only two of the non-resolvable ip6.arpa addresses resolved over v4.
fwiw, for those who have been asking, inbound SMTP is now working, and
I've got a basic IMAP/POP3 daemon running. If you still want a test
account, let me know.

Thanks everyone for all of the support.
