Technically you could return a keypair for the public user from userdb, when the public user is being looked up. mail_crypt_global_public/private_key takes precedence over generated keys.

Thanks. Tried that, and indeed with such a setup it is possible to have a global key for some accounts and folder keys for others.
But it does not work with public or shared mailboxes. A quick look at the source code revealed that mail-crypt plugin will not work with public mailboxes, but should work with shared mailboxes, even with encrypted folder keys. But this feature seem not to be documented very well...
I think I'll open another thread with appropriate subject to about this.
