Yes, Cydir is one possibility. You might also be able to do something
similar to zlib plugin. Opening existing encrypted files could be done
with a similar plugin, but you'd also need to make message saving write
the data encrypted. That probably can't be done without modifying
Dovecot's base code. Hmm. Actually it wouldn't require much, just
ctx->output would have to be moved to a public structure. Done:
