Those will get in. I'll use those lists with postfix, not on SA. Those guys who runs a mail server on such dynablocks, if, and only if, using their isp smtp, will have no problem at all. There will not be a Received: line on headers if, using their MUA, they connect to ISP and send the message. Those legitimate servers running on dynablocks, if properly configured and not relay-open, may be white-listed. > These will all get caught and trashed by > your plan.

We have sometimes 50-60% spam comming trough our servers. One day it got 80% SPAM! This overloads our servers (some old ones), our customers cannot pop their accounts from a dialup connection - imagine a 30MB MAILBOX, not maildir, popped from a 56K modem. I want to block those selling [EMAIL PROTECTED]@, asian porn, and such un-wanted material, which represents about 50% of the traffic (pure guess). There will be some spam that will then be easaly downloaded by our customers and then filtered. > > > > ------------------------------------------------------- > This SF.Net email sponsored by: ApacheCon 2003, > 16-19 November in Las Vegas.
