Applications use various Syslog-Facilities. Postfix uses $syslog_facility, per 
Default "mail". "auth" is a diffrent facility. You can filter in your 
syslog-Configuration for that facilities.

Ok, is the sql-Auxprop Plugin (libsql.*) installed? Best to check that.

In which Directory is the smtpd.conf? Which OS is that?

In the Log of your previous Mail is nothing to see from libsql, either your 
smtpd.conf is in the wrong Directory, or the Plugin is not installed.

MySQL does listen on an inet-Socket? (AFAIR Port 3306)?

Hmm, Passwords are unencrypted in your SQL-DB?

The smtpd runs chroot()ed, but because of the inet-Socket of mySQL, this does 
not matter.
