My results are obviously going to be more than the population at-large because I'm running an encryption server, but anecdotally, almost all of those are OpenPGP or S/MIME signature verifications.
Aha! So you could measure the ratio of PGP to S/MIME usage by message
from that. You could also count the number of distinct users for each
population.
As a proxy for PGP population, if you have the S/MIME population
estimate from somewhere, multiple that with the ratio, and you have an
estimate. Standard marketing calculations...
