There are many providers nowadays that are filtering on dynamic-looking patterns in DNS: bash-2.05a# nslookup 66.41.162.51 (original poster's IP) ... Name: c-66-41-162-51.mn.client2.attbi.com Address: 66.41.162.51 In fact, there are people who are publishing lists of patterns that match dynamic space for larger providers, to make this kind of filtering possible without provider's needing to list these nets in services like DUL. Filtering from dynamic space probably saves AOL from handling a HUGE amount of junk. Since most of the spam nowadays comes from hacked windows boxen on cable and DSL networks in dynamic space. There's little justification for end-users on dynamic IP's to be sending mail directly, rather than relaying through their provider's server. Which is also why many providers, especially large cable providers, are filtering outbound SMTP from their customers. _______________________________________________ TCLUG Mailing List - Minneapolis/St. Paul, Minnesota Help beta test TCLUG's potential new home: http://plone.mn-linux.org Got pictures for TCLUG?
