A user once asked:

I can’t seem to find the answer to this question anywhere on the Internet (it may just be me not fully understanding the standards), so I thought I’d ask you. If I have DMARC set up in my DNS (which I do) and also ADSP (also do), which one takes precedence? I’m also assuming that I am in overkill mode and that DMARC is enough. Your input would be appreciated when you have a moment.

About ADSP:

Given the above, we suggest removing your ADSP records to prevent the few sites that do implement it from doing the wrong thing.
