Hi everyone, I'm sure this is a commonly asked question, but searching the site for DKIM or Domain Keys brings up no results, so I'm posting here -- I hope someone can help.

We run a social network that needs, unsurprisingly, to email its users. Unfortunately, while @hotmail.com messages arrive for the most part without problems, all of our @yahoo.com / @sbcglobal.net messages are being flagged as junk... almost certainly because we don't have DomainKeys.

We are currently using IIS Virtual Server for our emails, but are thinking about upgrading to Exchange... provided it has DKIM and DomainKeys support. Unfortunately I cannot find anything anywhere that explains how this might be implemented in Exchange. Can anyone help?

Thanks for any assistance!

Hi,

A good question! and one which is not all that easy to answer.

Bascially, the simple answer is no. Exchange doesn't support domain keys by default.

I believe there is a solution out there although I think it needs some development work to implement.

Sorry not to have better news, hopefuly this is something MSFT might implement one day!

Cheers

Nathan

Hi, there is a third party application that enables MS Exchange to support DKIM/Domainkeys, and no programming is required. Refer to this url for the implementation:
