I'm having a problem getting Joomla to send the user registration / activation emails, and getting it to send the Test Email on the Server->Email settings section. I have multiple websites running on the server and they're all having the same issue. Joomla is up to date and PHP Version 7.0.23
I also tried just making a test php file:
<?php mail('firstname.lastname@example.org','This is a test message subject','This is a test message body'); echo 'Mail sent.'; ?>
No errors come up, but nothing gets sent. The mail.log file shows
[13-Oct-2017 00:56:30 UTC] mail() on [/path/public_html/website.com.au/dev/mailtest.php:2]: To: email@example.com -- Headers:
There aren't any email problems on other parts of the site.
I'm using PHP Mail - using SMTP is not really viable.
