There is a huge difference between the two, and a lot of people do not
care much about the latter.
For the former, given the lack of support for DK/DKIM signing in the two
most pervasive corporate email servers (Exchange and Lotus Notes), it's
reasonable to expect such mail *not* to be signed.

Maybe it's different for US-based providers, but I do not know of any
significant European provider doing DK/DKIM signing.
