Thanks for reporting. Kirby 3.5.5 has the latest version of phpMailer.

Sure? I have downloaded 3.5.5 and if I open the file phpmailer.php from /vendor/phpmailer/phpmailer/src/PHPMailer.php … I see in the comments header Version 5.5 (!)


  • PHPMailer - PHP email creation and transport class.
  • PHP Version 5.5.

Yes, i’m sure. It is not the phpMailer version. This is the lowest php version that phpMailer supports.
