Exchange 2007 Mail goes to customer junk folders
I seem to be having problems with email delivery. I have setup several SBS 2008 standard computers and most all appears to be going well. I’ve configured godaddy certificates, configured PTR records for reverse lookups, used MXTOOLBOX.COM to check settings, checked black lists to make sure we are not on any, etc. The problem is that much of the mail we deliver to customers ends up in their junk folder. I believe this is because the SCL rating of mail delivered is too high, 5 or so. I don’t know why we are getting such high ratings. I sent mail thru OWA, thru exchange with text only, and with only “test 1,2 or 3” in the subject and message body. No hyperlinks, pictures, nothing and yet the SCL is very high. Why? The domain is medspinedocs.com Thank you,

Are you using a POP3 connector? If so, that's an SBS component, not part of Exchange, so you'll get a better answer in the SBS forum: http://social.technet.microsoft.com/Forums/en/smallbusinessserver/threads Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

Another thought is that you, your ISP, and/or your IP address might be on a blacklist being used by antispam vendors. Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

Your A and PTR records could contain strings which other systems score as apammy as well (e.g. xxx-ADSLxxx or tw-static-xxx or similar which have in the past been known vectors for spam. If that is the case you may need to use a 3rd party relay such as MessageLabs for outbound mail.

No POP 3 connector, configured Hub Transport in Exchange for delivery.

I did not see the domain name on any blacklists, and again the issue is not that the mail is being blocked, rather that it is being received, but going into junk folders. Just can't figure why I'm getting high SCL scores.

The two machines I setup are in different locations and have different ISP's. Both were assigned static IP's, and worked fine with mail delivery from earlier versions of SBS2003. I still think it's something within the Exchange environment. One would think I could send an email to someone able to determine why their end scores the SCL high?

Hi, For this issue, I suggest you try to send emails to other domains to see whether this issue will happen or not? If this issue still happened, you can do an Outbound test at “test-website”, and follow the result to troubleshoot the problem. Here is the link for the test tool: https://www.testexchangeconnectivity.com/ If this issue does not happen, this may be the domain which you want sent email to has too high security level. For this issue, you can ask the administrator to lower the security level to have a try. Here is a related article for you: Understanding Spam Confidence Level Threshold http://technet.microsoft.com/en-us/library/aa995744(EXCHG.140).aspx If the problem persists, please feel free to let me know and I will be glad to help.
