Feature proposal #6981
closedUpdate PHPMailer
Description
PHPMailer 5.2.10 introduced Opportunistic TLS where it tries to establish a secure connection if the server advertises TLS is supported. However, if the server does this then provides an invalid certificate it will fail. Joomla has implemented a workaround to ignore this feature as shown below.

Don't agree with workarounds for, likely, incorrectly configured servers. Recommending updating to latest PHPMailer library to see if that helps improve the accuracy of Opportunistic TLS.
