Be aware that SASL and SSL aren't the same thing.

This is Postfix complaining. Have you told it to use dovecot for
authentication? For example, I have:
  # SASL SMTP Authentication
  smtpd_sasl_auth_enable = yes
  smtpd_sasl_security_options = noanonymous
  smtpd_sasl_local_domain = $myhostname
  broken_sasl_auth_clients = yes
  smtpd_sasl_type = dovecot
  smtpd_sasl_path = private/auth
  smtpd_sasl_authenticated_header = yes

http://wiki2.dovecot.org/HowTo/PostfixAndDovecotSASL will walk you
through getting postfix to talk to dovecot.

Are you able to receive mails correctly with Outlook? If so, you've
probably got dovecot working fine. If not, post the output of "doveconf
-n" here.
