User's guide to DKIM

DKIM stands for DomainKeys Identified Mail. DKIM can be thought of as a sort of digital signature on all of your mail. When you send out mail with DKIM enabled, it has your unique signature attached to it and the recipient's server can be certain of it's authenticity.

Consequently, if someone else sends mail under your name when you have DKIM enabled, the recipient (or their spam filter) will see that the mail doesn't have your signature and therefore is not authentic mail. This can occasionally have adverse affects when forwarding emails repeatedly, which can cause the recipients to receive email from a potential unsafe sender who does not carry your same DKIM signature, causing it to be incorrectly marked inauthentic, however, this is very rare.
