Nice. It worked but I think there is a little output error (probably not a big issue):

When I type the following command I get this output:

user'@'host:~$ doveadm -o plugin/mail_crypt_private_private_password=1234 mailbox cryptokey export -u username -U /var/vmail/domain/username/Maildir/dovecot-attributes Folder: Public ID: <Public key ID> Error: -----BEGIN PRIVATE KEY----- -----END PRIVATE KEY-----

And when I type the following command I get this output:

user'@'host:~$ doveadm mailbox cryptokey export -u username -U /var/vmail/domain/username/Maildir/dovecot-attributes Folder: Public ID: <Public key ID> Error: ERROR: error:03070068:bignum routines:BN_mpi2bn:encoding error Key:

So in the first command the private key shows but it's under Error, and I believe it should be under Key. Thanks again.
