This occurs when I try to send test emails to a subscriber email(s). They show “Success” but are never received. Yet when I use my admin email (what goes in the campaign’s From: field) it’s received. This was not an issue before v3.3.3.
I saw the earlier topic with the suggestion to reboot host that phplist is installed on, but as I have a shared not a dedicated hosting account that isn’t possible.
I’ve never used anything other than the default setting for sending campaigns, to wit:
// To use a SMTP server please give your server hostname here, leave it blank to use the standard
// PHP mail() command.
define('PHPMAILERHOST', '');
Any insights welcome.
UPDATE: I also tried adding this line to config.php but with that change phplist didn’t send out the test email or the campaign so I backed it out.
