I have a website hosted on server A. I use Cloudflare services, so I can not send mails to my users from the same server. I have server B for mail sending. Installed Exim and configured it as follows:
internet site, mail is sent and received directly using SMTP
Machines to relay mail for: [IP address of the server A]
On serevr A I use Phpmailer to send mail:
$mail->IsSMTP();
$mail->SMTPAuth = false;
$mail->SMTPSecure = "";
$mail->Host = "IP address of server B";
$mail->Port = 25;
$mail->Username = "";
$mail->Password = "";
Unfortunately, it doe snot work. Tried to change $mail->SMTPAuth to "true" but it does not help.
SMTP Error: Could not connect to SMTP host.
