OT: DKIM, ADSP & ARF opinion requested

[Patrick Ben Koetter]

I am doing research for an article related to the current state of DKIM and
ADSP usage. Please reply to me offline if you want to share your opinion or
experience:

- Do you know DKIM?
- Do you know ADSP?
- Do you know ARF?
- Do you use it?
- If not, why?
- If yes, why?
- What are your experiences?
- Do you run statistics?
- What do they say?

Thanks!
