Hello Steffen,

I do encrypt/decrypt email on-the-fly for months now with the help of
mail-filter plugin.
It works perfectly as long as the decrypted email is exactly as it was
before it was encrypted, which is the case with my bespoke
encrypt/decrypt programs.
That is not the point I raised in this thread. The point is that, in a
specific circumstance, Dovecot is trying to read an email that has been
encrypted without having the user this email belongs to authenticated.
