Currently it suggests to use pam as pwcheck_method, while it should use saslauthd. the pwcheck_method seems to do not work while the saslauthd correctly authenticates with pam (with the stock sasl configuration)
postfix and sasl still only works with /etc/sasl2/smtpd.conf be linked to /usr/lib/sasl2. This is valid for cyrus-sasl-2.1.22-r2, postfix-2.4.5, amd64 hardened
