[4.0] SMTP connection fails without SSL/TLS #24241
Description
Related PR #23591
Steps to reproduce the issue
Try to connect to an SMTP server without any SSL/TLS security option turned on
Expected result
Connection is successful as in Joomla 3.9
Actual result
Connection fails and doesn't fallback anymore to a new one without a secutiry layer
It's not possible to connect to SMTP server without any SSL/TLS because $SMTPAutoTLS in the PHPMailer class is always true and not managed in any way by the mail class or Joomla options.
Additionally, even SSL/TLS options fail to connect to the SMTP server if enabled.
System information (as much as possible)
Joomla 4.0 Alpha 8
Additional comments
This is the result to have removed the following code in the Mail class within the Send function:
try
{
// Try sending with default settings
$result = parent::send();
}
catch (\phpmailerException $e)
{
$result = false;
if ($this->SMTPAutoTLS)
{
/**
* PHPMailer has an issue with servers with invalid certificates
*
* See: https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting#opportunistic-tls
*/
$this->SMTPAutoTLS = false;
try
{
// Try it again with TLS turned off
$result = parent::send();
}
catch (\phpmailerException $e)
{
// Keep false for B/C compatibility
$result = false;
}
}
}
