IP used in the HELO request

Hello,

I was testing my email on mail-tester.com and and i got this error:

-1.999   FSL_HELO_BARE_IP_2   IP used in the HELO request
The hostname should be a domain name, not an IP address

I have checked my postfix configuration in CWP and it has a valid hostname.

Anybody knows whats wrong?

Thanks 

same problem. any one ?

no one can help

solve to my self

go to...

/usr/local/apache/htdocs/roundcube/config/defaults.inc.php

find the..

$config['smtp_helo_host'] = '';

and replace to

$config['smtp_helo_host'] = 'mail.yourhostname.com';

Hello.

I guess you have using webmail by link like http://server_ip/webmail . But it should be http://your_domain/webmail
