Reply To: Quform PHP stopped working. Please we need urgent help

With the help of technical support, we found that the cause of the problem was the lack of SMTP authentication. It seems to be necessary now.
After the setup, Quform PHP worked for us again without any problems.

$config['smtp'] = array(
'host' => '',
'port' => 25,
'username' => '',
'password' => '',
'encryption' => ''

Is it recommended that we also set “encryption”? We have left it blank for now.
