I am using postfix and dovecot along with zpanel and I tried enabling SSL and then turned it off as I did not have SSL configured yet and I realized it was a bit stupid at the time. I am using CentOS 6.4.

I get the following error in the mail log. (I changed my host name to "myhostname" and my domain to "mydomain.com")

Oct 20 01:49:06 myhostname postfix/smtpd[4714]: connect from mydomain.com[127.0.0.1]
Oct 20 01:49:16 myhostname postfix/smtpd[4714]: fatal: no SASL authentication mechanisms
Oct 20 01:49:17 myhostname postfix/master[4708]: warning: process /usr/libexec/postfix/smtpd pid 4714 exit status 1
Oct 20 01:49:17 amyhostname postfix/master[4708]: warning: /usr/libexec/postfix/smtpd: bad command startup -- throttling

Reading on forums and similar questions I figured it was just a service that was not running or installed. However I can see that saslauthd is currently up and running on my system and restarting it does not help.

Here is my postfix master.cf
