ps auxww|grep smtp
ls -l /var/spool/postfix
ls -l /var/spool/postfix/etc/postfix/sasl_passwd.db (you run chrooted 
right?)

or grep 'postfix/smtp\[' /var/log/maillog
and look for messages related to sasl and/or sasl_passwd.db

the smtp daemons will run as postfix user and so sasl_passwd.db has to 
be readable by postfix user.
