iRedMail uses STARTTLS by default, of course you can configure Postfix manually to use SSL. But, SMTP over SSL (port 465) is deprecated, the recommended one is SMTP over STARTTLS (port 587, the iRedMail default setting).
I am not much aware of STARTTLS. I believe that it gives a secure encrypted connection as SSL. I hope it will give a password encryption too. I am more concerned about the security. Please suggest.
