Given the NSA IAD Commercial National Security Algorithm Suite letter
(URL: https://www.iad.gov/iad/programs/iad-initiatives/cnsa-suite.cfm)

The trend seems to be against P256. Of course, "top secret" documents
will NOT be sent via SMTP in any case.

If what I heard at the ICMC17 conference this year is correct, then I
believe that Ed 25519 and/or Ed 448 will be getting added to the list of
approved algorithms before too long (within the next year).
