You are welcome, I'm an ADSL subscriber myself. 8-)

That's exactly why I use my own, homegrown blacklist.  All entries
were made after I received spam or Windows worms from addresses whose
reverse suggest that it's some kind of mass-market Internet access

However, there is a certain twist in my MTA configuration.

Your MTA uses a HELO/EHLO argument which is (a) valid (the forward
lookup matches your server's IP address) and (b) different from your
reverse lookup.  This overrides my blacklist, and your mail should
pass through.

It's a hack, but it works remarkably well, and it helps in cases like

Current mail filters: many dial-up/DSL/cable modem hosts, and the
following domains: atlas.cz, bigpond.com, di-ve.com, hotmail.com,
jumpy.it, libero.it, netscape.net, postino.it, simplesnet.pt,
tiscali.co.uk, tiscali.cz, tiscali.it, voila.fr, yahoo.com.
