It is a little bit of both. Some dynamic IP addresses will be blocked because they are dynamic and some don't. The forward and reverse lookup is a complete different thing. every ip address and domain in e-mail traffic must be forward and reverse resolvable. sometimes it works without, but most of the time it don't. > > Stef Martin -- ------------------------------------------------------------ H E L I X Gesellschaft für Software & Engineering mbH ------------------------------------------------------------ Hanauer Landstrasse 52 Telefon (069) 4789 35-30 D-60314 Frankfurt am Main Telefax (069) 4789 35-44 ------------------------------------------------------------ http://www.helix-gmbh.net [EMAIL PROTECTED] ------------------------------------------------------------
