De la Wiki de postfix[1]:
Hiding SASL authentication from clients or networks
Some clients insist on using SASL authentication if it is offered,
even when they are not configured to send credentials - and
therefore they will always fail and disconnect.
Postfix can hide the AUTH capability from these clients/networks:
/etc/postfix/main.cf <http://www.postfix.org/postconf.5.html>:
smtpd_sasl_exceptions_networks
<http://www.postfix.org/postconf.5.html#smtpd_sasl_exceptions_networks> =
!192.0.2.171/32, 192.0.2.0/24

Saludos...
