Start from scratch.

Postfix and cyrus-sasl-lib are installed by default on CentOS 7.

Edit /etc/sasl2/smtpd.conf with

pwcheck_method: auxprop
mech_list: plain login

Create your /etc/sasldb2 running

saslpassd2 -u localhost roelof

And finally enable SMTP AUTH for Postfix by

postconf -e "smtpd_sasl_auth_enable=yes"
systemctl restart postfix

(Note: once finished these basics move on and enable SMTP AUTH only for 
submission and remove it from SMTP port 25.)
