DKIM

[Alice Wonder]

DKIM is a very useful tool for identifying whether or not a message was sent through an appropriate SMTP server for the domain the message claims to be from.

Instead of using the standard DKIM header to indicate the signature, Google uses their own special header called X-Google-DKIM-Signature that results in it not being recognized by a lot of software, so the benefits of DKIM are not there.

Why does Google have to do crap like that? Seriously, why?

Things like that are why I despise Google as a company, really despise them.

Where are you seeing this? I just tried sending a message from my
Gmail address to a Hotmail address and the standard DKIM-Signature
appears in the headers. I suspect with a name like
"X-Google-DKIM-Signature", it would only be seen internally.

I'm not seeing this either Alice. Can you give us an example, and also what software is not recognising the DKIM header?
Looking at the source of your email to this group I am only seeing the usual 'DKIM-Signature:' header. I also sent myself a test message from my Gmail address to an external address and get the same, correct header.
