Hello VictorBH,

 

Welcome to the WHMCS Community Forums!

 

Regarding the issue you are facing this is likely caused by the AutoTLS setting in phpmailer. To resolve this issue you'll simply need to edit the file located at /vendor/phpmailer/phpmailer/class.phpmailer.php in your WHMCS installations and change the $SMTPAutoTLS value to false.

 

Please remember to take a backup of the file before making any changes.

Many hosts have disabled the PHP Mail for security reasons. Try SMTP
