<p>Maybe. I receive lots of spam, but so far I have not received any
encrypted spam. That would not be hard, spammers could retrieve my
PGP key from a number of key databases. But they don't bother, and
I wonder why. Is it because the users of something like PGP are
somehow so smart that the spamĀ will immediately be rejected? Or
is it because as PHB says, it would reach maybe just 0.05% of the
global email market, and that would not be profitable? But if the
latter, wouldn't encrypted email be a wonderful channel for a
spear-phishing attack?</p>
