Re: Warning - Reverse DNS does not match SMTP Banner

It says "SMTP Banner".

In Postfix, smtp banner is below setting by default (iRedMail doesn't change it):

smtpd_banner = $myhostname ESMTP $mail_name

So, the error complains the hostname in "$myhostname" setting doesn't match, not your mail domain name.
