Re: [Declude.JunkMail] Spamdomains test

[Matt]

I've been planing on trying this for about a week now, and I'm still not convinced that it will work.  From my standpoint though, this represents a good way to remove a tad bit more processing and maintain a system to be shared on multiple servers without having to update text files. This idea originally came from my desire to qualify two pieces of information when whitelisting.  Using this technique, you could effectively whitelist without fear of forging, though of course the possibility would still exist.  You could credit messages that pass such a test such as from amazon.com, coming from an amazon.com reverse DNS entry, and that would be much stronger than systems like BondedSener which relies only on the IP, where servers can still be hijacked or infected.  This is also a much more efficient way to credit messages than to maintain long lists of whitelist address and as above, it's a good format for a distributed system with multiple scanning servers that can be updated in real-time. My biggest wish though is that both the To: address and the Reply-To: address were exposed through variables and filters, because that would allow me to apply credit to things that use VERP and also put it in DNS instead of using body or header filters to do the dirty work.

For instance: MPBL-SPAMDOMAINS dnsbl %REVDNS%.%RHSBL%.spamdomains.example.com 127.0.0.2 4 0 Interesting idea, Matt. Still way too much management compared to SPF-compatible formatting, though. The ability to append ._spf.example.com to SPF queries, or use the SPFDOMAINS text list, would be a lot easier. --Sandy ------------------------------------ Sanford Whiteman, Chief Technologist Broadleaf Systems, a division of Cypress Integrated Systems, Inc. e-mail: [EMAIL PROTECTED] SpamAssassin plugs into Declude! http://www.mailmage.com/products/software/freeutils/SPAMC32/download/release/ Defuse Dictionary Attacks: Turn Exchange Addresses into IMail Aliases! http://www.mailmage.com/products/software/freeutils/exchange2aliases/download/release/ --- [This E-mail was scanned for viruses by Declude Virus (http://www.declude.com)] --- This E-mail came from the Declude.JunkMail mailing list.
