Hello all, I followed the guide http://www.howtoforge.com/perfect-server-centos-6.2-x86_64-with-apache2-ispconfig-3 on CentOS 6.2 on VPS. Installation was smooth but email not working at all , not even sending to user email itself. I am not sure where to start looking. Mar 20 23:09:50 server postfix/smtpd[4030]: fatal: no SASL authentication mechanisms I got it working , I found the answer from http://www.electrictoolbox.com/postfix-smtp-auth-no-sasl-authentication-mechanisms/. I installed yum install cyrus-sasl-plain and started to get working. May be that should include in the guide.
