Reverse DNS gives a lot more credibility to your domain as it requires
the intentional participation of the netblock owner (or the ISP the IP

reverse in there, that says to the world you're no different then the
infected Windows user down the street. Go through the effort to
legitimize your server and you'll get your mail through. In most
circumstances an ISP won't give you a reverse DNS on a dynamic IP.
I am pursuing this line as well... This particular ISP won't set rDNS
to correspond to a dyndns.org domain, but if I purchase my own
"official" domain and show them the RIPE records they will set rDNS.
So I'm currently looking into getting a pukka domain through an agency
which will proxy the contact information (so as not to blurge my
postal address all over the WWW) without charging a fortune for it.
There are a vast number of possible domain name registration agencies,
so the research isn't exactly speedy :-)
