Hey guys, I am currently running exchange 2010, I have implemented SPF record, and tried to implement dkim/domain keys using domain sink, but it doesn't seem to work. The problem I am having is that all my emails go to spam, whenever I email some one whether it is msn/yahoo/gmail. For Msn i fixed it, since I subscribed to senders framework program.

here are the orignal copies of Gmail and yahoo:

========================================================== Explanation of the possible results (adapted from

draft-kucherawy-sender-auth-header-04.txt):

"pass" the message passed the authentication test.

"fail" the message failed the authentication test.

"softfail" the message failed the authentication test, and the authentication method has either an explicit or implicit policy which doesn't require successful authentication of all messages from that domain.

"neutral" the authentication method completed without errors, but was unable to reach either a positive or a negative result about the message.

"temperror" a temporary (recoverable) error occurred attempting to authenticate the sender; either the process couldn't be completed locally, or there was a temporary failure retrieving data required for the authentication. A later retry may produce a more final result.

"permerror" a permanent (unrecoverable) error occurred attempting to authenticate the sender; either the process couldn't be completed locally, or there was a permanent failure retrieving data required for the authentication.

The following is based off of the IP I see in your logs as the mail sending IP of 67.55.9.182.

You have a PTR entry, which is good.

;; ANSWER SECTION:
182.9.55.67.in-addr.arpa. 14400 IN      PTR     dsl-67-55-9-182.acanac.net.

However your forward and reverse should match ideally. The reverse entry leads me to believe that you are running this off of a DSL ISP connection. That is enough to get your mail marked as spam in some systems. They do not like seeing mail coming from "home" or "consumer" connections.

Your IP is also listed in several blacklists:

67.55.9.182 is listed in dnsbl-3.uceprotect.net 
67.55.9.182 is listed in bl.spamcannibal.org

This will also result in your mail being sent to the spam bin.

Resolve the above issues and you will likely see your mail being accepted as ham. Hope that helps and let me know if you have any questions.

  • I checked spamvannibal, and it says that i don't have a reversedns, and uceprotect, and they are saying that my whole isp is flagged as spam. Now for the reverse DNS, can I create a reverse DNS from the dns server in server 2k8 and then if it does a reverse look up, will it come to my domain name? –  Jan 28 '10 at 18:22
  • Reverse DNS is handled by your ISP. Any PTR is likely not delegated to your local Windows Server 2k8 and any that you add would not be recognized across the internet. Unless you have some special setup from your ISP. – Dave Drager Jan 28 '10 at 18:41
  • So what are the possible solutions, if I can't add a reverse DNS, and a PTR? Can I ask my ISP to put a PTR pointing from static IP to my domain:SamChrisNetwork.info? would this help? Also, how can I implement DKIM in my server? –  Jan 29 '10 at 03:25
