Reverse DNS does not match SMTP banner

[mayrmart]

Hi,

I am new to efa.
Just installed it first time and seems to work great
Just one small problem.
http://mxtoolbox.com/diagnostic.aspx is not really happy with my SMTP banner.

SMTP Banner Check Reverse DNS does not match SMTP Banner

Cant find where to change.

Thanks

Does your forward DNS entry (MX) match your reverse DNS entry (PTR) in your public DNS?

You can also telnet to your host on port 25 to check out your SMTP banner.

Thanks.

found it

in /etc/postfix/main.cf

smtpd_banner = ESMTP EFA [your host name]

Can someone clarify?
I'm running EFA 3.0.1.1 and in my main.cf smtpd_banner is commented and yet my rDNS seems to work just fine so where is it coming from?

Postfix supplies a default banner based on the domain name defined in postfix if a custom one is not specified.
