You need to set properly smtp_helo_host option in config/main.inc.php file.

OK! I found: /etc/roundcube/main.inc.php; var/lib/roundcube/config/main.inc.php.
Which one should be edit? Both files in the smtp_helo_host_option section are this: rcmail_config['smtp_helo_host']=  '' ;
What and what needs to be replaced? Thanks.
