I have only run into one instance of such a picky-server problem, and
I've been in the situation for a couple of years. My home subnet is
statically assigned but the [IPv4] ISP won't point the PTRs to my
names, although the forward mappings, which are under my control,
point to the ISP-assigned addresses. The only problem this seems to
cause is that the MX servers for aol.com won't accept my email unless
I funnel it through the ISP's smtp server.
All other servers seem to be satisfied as long as there's SOMETHING
in the in-addr.arpa.
