Alright, using postconf debug_peer_list appears to have identified the issue:

I modified the following:
main.cf - smtpd_tls_security_level = encrypt CHANGED TO may
master.cf - -o smtpd_tls_security_level = encrypt CHANGED TO may
1. there's no need to configure the same option in master.cf than in the
main.cf, it's required when you want to change them.
2. submission and smtps SHOULD have "-o smtpd_tls_security_level = encrypt",
clients should be required to both authentize and encrypt.
