Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

Yahoo Mail is sending our server's transactional emails to the Spam folder, even though we have taken quite a few anti-spam steps. By contrast, Gmail allows the messages through to the inbox just fine. Here are the things which are in place:

  1. SPF is set up for the domain holsteinplaza.com. Yahoo reports spf=pass in the message headers.

  2. DKIM is set up for the domain holsteinplaza.com. Yahoo reports dkim=pass in the message headers.

  3. We have a proper reverse DNS entry for the sending mail server. Name -> IP matches IP -> Name.

  4. Neither Domainkeys nor SenderID are set up. From what I can tell, DKIM is the way of the future, and there is not much to be gained from adding Domainkeys or SenderID.

Following are the headers. Any ideas what more I should do to get Yahoo to stop flagging the emails as spam?

"X-YahooFilteredBulk" you might check your mailer to ensure it is not tagging the messages as "bulk" and/or check with Yahoo on how that determination may be triggered on their end.

Yahoo rely on DomainKeys and it did the trick for my setup. DomainKeys are not the same as DKIM, although very similar. You can read more here and here.
