Let me try again. So the email comes in. Some programs gets your public key and then encrypts the email on the server. Then when you retrieve your email, it sends it out in what it believes is plain text or for that matter can to TLS on the file, but you get a GPG message that you then decrypt.

I thought this was a directory ownership problem. /var/mail/vmail/... was owned by dovenull:dovecot. In any previous Dovecot+Postfix installation I've had, it's been owned by postfix:postfix. using chown on this directory tree didn't fix the problem: Oct 26 12:54:28 theglobalvoice postfix/loc
