Re: [Declude.JunkMail] Using RHSBL's for reverse DNS entries
Currently, to the best of my knowledge, 'rhsbl' tests in Declude only work on the Mail From and not the reverse DNS value. I'm interested in the reverse DNS value to be added. BTW, there are a couple of additional tests that MailPolice added at the end of April that weren't on that list: adv.rhs.mailpolice.com (http://rhs.mailpolice.com/index.php#rhsadv) Domains used by e-mail marketers. This includes legitimate opt-in subscription mailing lists and newsletters. This list should never be used to block e-mail in site-wide configurations! It will surely block legitimate and important e-mail that users have opted-in to receive. This should only be used by user-configurable filters, or possibly as a white-list for people who wish to receive solicited advertising. webmail.rhs.mailpolice.com (http://rhs.mailpolice.com/changes.php) For listing webmail providers (Matt's note: this could be useful in a combination filter).

Re: [Declude.JunkMail] Using RHSBL's for reverse DNS entries
That would be awesome if it really does work. I'll give it a try this evening! Am I also to assume that this will work with the %HELO% as well? That would rock :) Just a note of caution to others, if you use MailPolice Bulk on the Mail From, and you try this technique, you probably don't want to be scoring a double hit, instead a combo filter using TESTSFAILED to assess one value for either failure would be the best, i.e. - MailPolice.txt - TESTSFAILED 0 CONTAINS MAILPOLICE-BULK TESTSFAILED 0 CONTAINS MAILPOLICE-BULK-REVDNS ...and then give it one score in the Global.cfg.

Re: [Declude.JunkMail] Using RHSBL's for reverse DNS entries
For the test type below you have dnsbl ; I have only been using rhsbl and ip4r - are these just names to flag the type of test in global.cfg or are different actions taken on each? [Hope I am somewhat clear on this..] That is correct. ip4r will take the IP address that the E-mail came from, reverse it, and add it to the zone that you supply. So an E-mail coming from 192.0.2.25 using the zone bl.example.net would use 25.2.0.192.bl.example.net. rhsbl will take the domain in the return address and add it to the zone that you supply. So an E-mail coming from [EMAIL PROTECTED] using the zone bl.example.net would use example.com.bl.spamcop.net. dnsbl will just use the zone that you supply. So if you use %REVDNS%.bl.example.net, an E-mail coming from the IP 192.0.2.25 that has a reverse DNS entry of mail.example.com would use the zone mail.example.com.bl.spamcop.net. -Scott --- Declude JunkMail: The advanced anti-spam solution for IMail mailservers since 2000.

Re: [Declude.JunkMail] Using RHSBL's for reverse DNS entries
So in the global we'd have: First the actual tests with no value for failure MAILPOLICE-BULK-REVDNS dnsbl %REVDNS%.bulkk.rhs.mailpolice.com * 0 0 MAILPOLICE, etc. Then the Filter (Using the example construct below) with a weight MAILPOLICE filter X:\imail\declude\MailPolice.txt x 10 0 Is that correct?
