That's interesting. I have Qwest's VDSL in Chandler. Port 80 is open.

Your (any) location will have either VDSL or ADSL available (not both), and
static addresses are not possible with VDSL. Sending mail from a server on a
dynamic address has become more of a problem lately (over the last 6 months
or so) as various RBLs (zen.spamhaus.org in particular) have added dynamic
pools to their block lists. I use dyndns.org's mailhop service (which is
reasonably affordable) to circumvent this problem.
