What does that have to do with providing MTA CLIENT-side SASL_AUTH support?

Do you not know the difference between smtpD_sasl and smtP_sasl?

Server-side = smtpd

Client-side = smtp

Currently  the only way postfix can perform CLIENT-side sasl_auth is 
with cyrus-sasl, because dovecot_sasl doesn't support it, and never has.

No clue what you're talking about here...
