    Default Reverse DNS does not match SMTP Banner

    Hello

    I use mxtoolbox to test - > smtp:Test mail server SMTP (port 25)


    Then I become warning: Warning - Reverse DNS does not match SMTP Banner


    How to fix that ??


    I read on forum, that I have to change main.cf (smtpd_banner).

    Have someone did that ??


    In my main.cf I found:
    smtpd_banner=$myhostname ESMTP $mail_name

    What I have to change?


    Thanks all
