RE: [Declude.JunkMail] Why did this fail reverse DNS

Hi Darin,   Thanks for the response.   I host my own primary nameserver here, which is also the same box as my IMAIL server. There is no upstream DNS server involved. That's what has me so puzzled on this.   I have relay set only for IP addresses, my users don't authenticate. In order for them to send mail, they must be VPN'd in and receive an IP address that is reserved for VPN clients only. (Long story on this) In this case, I don't believe Whitelist Auth will work, unless it can be based on IP addresses, rather than user authentication.   Sharyn     -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Darin Cox Sent: Wednesday, September 07, 2005 12:38 PM To: Declude.JunkMail@declude.com Subject: Re: [Declude.JunkMail] Why did this fail reverse DNS Hi Sharyn,   How is DNS configured on your server?  Are you using upstream DNS servers that are suddenly not resolving?  We've had that problem in the past, and resolved it by not using forwarders to provider DNS servers in our local DNS server on the IMail server.   If you use WHITELIST AUTH in your Global.cfg, you can eliminate a lot of these problems as well, like CMDSPACE that MS mail clients fail.  With that setting, all users who authenticate when sending will be whitelisted.

All of a sudden, my own users are failing tests that they were passing last month. Here is the spam attachment that Declude adds to our emails, if the weight is 10. You **MAY** have spam!
