To prevent spam & malware attacks, PHPmail is disabled by default.
In order to avoid blacklisting of our mail servers due to unprotected contact forms & other forms, the forms must be secured with Captcha, e.g. (re-captcha v2) this is required to use PHP mail.
If your application does not support PHP mail at the moment, please let us know when a captcha protection has been integrated and therefore the PHP mail function should be activated.
The captcha plugin must be set up as a mandatory field so that the form cannot be sent without checking the captcha.
You can request PHPmail activation via a support ticket.
