Hi there...
1) Open your file: config.inc.php
Path:
Code: Select all
/etc/roundcubemail/config.inc.php
2) Add a line:
Code: Select all
$config['smtp_helo_host'] = 'localhost';
3) Save/Exit and Reload
exim, dovecot, spamassassin , clamd
OS: CentOS

I had this problem in vestacp and resolved it by updating the variable smtp_helo_host to localhost in the file
/etc/roundcubemail/defaults.inc.php
Code: Select all
$config['smtp_helo_host'] = 'localhost';

HI,
Thanks, the config.ink.php modification, works for me.
I have two vps (centos7 vesta) and I had this problem with only one vps with exactly the same configuration.
