Or was that 'dynamic ip (dsl and cable)' and not '(dynamic ip dls) and cable'?Sloppy wording on my part, so thanks for bringing it up. You had it right: dynamic IP DSL and dynamic IP cable (not too common, these days). I believe that some "dial-up" lists also include static IP cable netblocks where the provider has stated that customers in these netblocks are not permitted to run a mailer (at least they used to include those). If you do this with reasonable care, you will rarely get a false positive. When you occasionally do, it will generate a DSN, not get silently dropped as with a content filter. No disappearing email and no dozens of false positives. If some of your correspondents insist on running rogue mailers, whitelist them and/or ask them to get a legitimate setup. I agree with that policy, but what lists are you using? My main worry is that there are maybe list maintainers that go around and see 'oh that looks like a netblock used for dynamic dsl', without having hard data to back up this claim. Koen -- K.F.J.
