ThinkDKIM for IIS SMTP

Digitally sign your IIS SMTP outgoing emails, making their origin and content trustworthy while improving your reputation and preventing them from being flagged as spam by services such as Hotmail, Yahoo Mail and Gmail. DKIM provides businesses an industry-standard method for mitigating email fraud and protecting an organization's brand and reputation. ThinkDKIM hooks itself to the SMTP service pipeline, adding a special header containing a digital signature of the message's content using a pre-defined private-key. Verifiers like Hotmail, Yahoo Mail and Gmail will later on retrieve the matching public-key from a pre-defined DNS TXT record, and verify the message's origin and integrity.
