Malcolm: Thanks for your opinion: In using the qpsmtpd plug in to guess dialups to reduce junk mail, I have been able to eliminate about 85% of junk mail that Courier was having to deal with, and just about all virus-spreading attempts. Thus far I have found one company whose RDNS was incorrectly set, whom contacted me and I put them into a whitelist.
If you know of a better way to get rid of Junk Mail coming from bots and zombies, I'm all ears. I already tried using a few RHSBL lists, but that kept blocking some legitamite mail so I stopped using it. Thus far, QPSMTPD and its related plugins that I have enabled (check_earlytalker, nodialup, check_relay, dnsbl, check_spamhelo, check_basicheaders, check_goodrcptto, virus/clamav) has been the greatest and most configurable filter I've seen thus far. I'd like to configure it Better, yes, but when foraging on ones own with little time to spare and no budget to work with, I've got to go with what works. -Ray -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Malcolm Weir Sent: Friday, September 12, 2008 12:03 PM To: [email protected] Subject: Re: [courier-users] Courier will not deliver to a Cloaked MTA? And another thing... Ray, This sort of nonsense: "<[EMAIL PROTECTED]>: loraninc.com [216.117.220.102]: <<< 550 Sorry, h-74-0-35-146.snfccasy.covad.net (74.0.35.146) seems to be a dialup: use your ISP's SMTP server, or Fix your RDNS. If you feel you are receiving this message in error, please call us at +1-800-544-4840" Is complete BS. Making judgements about whether or not something is a "dialup" hasn't been a useful tool for years, even when you got it right. In this case, you haven't, and that IP is not a dialup (it's DSL, but as static as a T1 -- just faster). FWIW, the RDNS exists, and is "fixed", IAW the RFCs. So you may want to rethink that whole idea...
