MAR-196: Simplify allowed TLS protocol configuration for mail_server role:

- Accept minimum version allowed instead of arbitrary list.
- Fixes deprecation warnings in Dovecot logs (ssl_protocols ->
ssl_min_protocol transition).

# Authentication configuration.
auth_mechanisms = plain login

  driver = ldap

  default_fields = uid={{ mail_user }} gid={{ mail_user }} home=/var/{{ mail_user}}/%d/%n
}

# Mail storage configuration.
mail_location = maildir:/var/{{ mail_user}}/%d/%n/Maildir
namespace inbox {
  inbox = yes
  separator = {{ imap_folder_separator }}
}

# Communication with other services.
service auth {
  unix_listener /var/spool/postfix/private/auth {
    mode = 0660
    user = postfix
    group = postfix
  }
}

# TLS configuration.
ssl_cert = </etc/ssl/certs/{{ ansible_fqdn }}_imap.pem
ssl_key = </etc/ssl/private/{{ ansible_fqdn }}_imap.key

# Mail delivery.
