nova Posted April 15, 2004 Share Posted April 15, 2004 Hi Guys, My first post here. Now i have a optin list that i send out a weekly newsletter to. The list is double optin and only those people who specifically sign up are sent this mail and they can unsubscribe at any time. Its all automated. I recently felt paying money for a autoresponder was actually a waste and i decided to run the list from my own webspace using a software called autoresponse plus. I signed up for hosting and noticed that some domains dont accept the mail for delivery and return the message. "This message was created automatically by mail delivery software. A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed: xxxx[at]vsnl.com SMTP error from remote mailer after MAIL FROM:<xxxx[at]thedomain.com> SIZE=5711: host mx3.vsnl.net [203.200.xxx.xxx]: 550 5.1.8 invalid/host-not-in-DNS return address not allowed" I have removed the address portions for privacy and added "xxxx" in their palce Now at first i thought that the ip address might be blacklisted and so i tried it out here at spamcop and found that the domain is not blocked, but rather that the reverse dns is not enabled. I then came to realise that a lot of domains dont accpet mail for delivery if the reverse dns is not enabled. When i wrote to my webhost his reply was this: I can add an RDNS to your server if you want, but we purposely have some servers with without RDNS because your spam complaints will increase with an RDNS,. More email will go thru, but you’ll get more flames. Most clients prefer to not risk spam complaints. These days it only takes about 2 complaints for you to lose your account. Some web hosts terminate you after one complaint. I watch how much mail goes thru and how much doesn’t and what doesn’t go thru is minimal. When i asked him how specifically RDNS would increase my spam complaints this was his reply Servers with RDNS enabled just get thru their itineraries more often thru the more difficult networks. When your emails (including double-opted in autoresponders) make their way thru those relays that are more stringent on what they accept, you will, statistically receive more spam complaints. Not just because more email gets thru, but because of the kind of places it is getting thru to. For example, since AOL is the MOST stringent in receiving outside emails (they now filter almost 100% of emails that come from privately owned domains being hosted on smaller company servers), So, if you DO get thru to AOL with your domain it can be good news that your email got thru and Bad news that it got thru to an ISP that allows people to accuse you of spam at the click of a button.. When this happens, you are guilty of spamming no matter what “proof” or argument you present. On the other hand…some of the more lenient and smaller ISP’s do not require an RDNS to receive email traffic and hence, have less stricter policies. It’s all a numbers game that is bigger than any one person or one web hosting company. The bottom line is, if you are going to use the technology of email for business (and I have since Feb or 1996)…you need to have other options, alternatives and work-arounds for communicating with your audience. Email is NOT fail-safe nor is it as reliable as conventional forms of communication. Also, an RDNS is simply a very basic and crude security mechanism. Some servers want you to have one to get thru – some don’t. I have done both for many years and the affect has been minimal. I still operate my business 100% with the use of email communication AOL says they require ALL email that comes thru to have an RDNS…then they still filter it if someone clicks the “spam” button – whether you have an RDNS or not. It’s not fair – it’s no fun. It’s the way the Internet works, and while it is still in it’s infancy – people figure out ways around it. . Sorry if this post was kinda long, but what i really need to know is 1) Does Enabling Reverse DNS for my domain incraese my chances of a spam complaint? and if yes how so? 2) Any idea how many providers require RDNS enabled to accept mail for delivery Thanks Nova Link to comment Share on other sites More sharing options...
