Possible problem with SMTP HELO

Postby jorgebastos » Sun Apr 06, 2014 3:54 am


I've been trying to send emails, but spamassassin keep's reporting that I'm sending spam, my own and foreign.
The highest score it reports is about HELO command:

2.0 HELO_NO_DOMAIN Relay reports its domain incorrectly

On the webserver that OJS is installed, HELO is required, so maybe OJS is not sending the right information to it.
Is this know, or OJS doesn't send HELO by default, or is there a parameter to?

Thanks in advanced,
Jorge Bastos

Hi Jorge,

The HELO command is sent in lib/pkp/classes/mail/SMTPMailer.inc.php in the "mail" function:

Code: Select all

// Send HELO/EHLO command
$serverHost = preg_replace("/:\d*$/", '', Request::getServerHost());
if (!$this->send($this->auth ? 'EHLO' : 'HELO', $serverHost))
    return $this->disconnect('Could not send HELO/HELO');
The server host comes from the $_SERVER variable in the following order of precedence:
I'd suggest using an error_log statement in the email sending code to dump out what it's currently using and debugging from there.
