Agreed. I generally test by sending a message to my GMail account. If it says "Signed by:" in the header details, I'm satisfied that I'm successfully sending mail with valid DKIM sigs. If anyone else says it fails, it's likely they're breaking it themselves. GMail isn't infallible, but they're reliable enough to depend on for testing. SteveJ
