Postfix delegates the authentication in SMTP Authentication to Cyrus
SASL. If you want SASL to use an SQL "authentication backend", in your
case MySQL, you have to configure SASL to do so.

Postfix is totally unaware of the authentication backend SASL uses and
currently there is no other SASL support in Postfix, where Postfix would
use its own MySQL capabilities to query an authentication backend for
valid credentials.

If at all, it would be another yet to be created Postfix daemon that
would handle this. At least that is the latest news I read on
postfix-devel.
