Thread:Project:Support desk/PHP mail()/reply (3)

Hello again!Thanks for your help and I checked code about SMTP as following: /** * SMTP Mode. * * For using a direct (authenticated) SMTP server connection. * Default to false or fill an array : * * @code * $wgSMTP = array( *    'host'     => 'SMTP domain', *     'IDHost'   => 'domain for MessageID', *     'port'     => '25', *     'auth'     => [true|false], *     'username' => [SMTP username], *     'password' => [SMTP password], * ); * @endcode */ $wgSMTP = false;

This is the code about SMTP in DefaulingSettings and does it mean that the service of SMTP was not used?

And I checked errorlog, there was an error that:sh: 1: /usr/bin/sendmail: not found

I was really confused due to my limited knowledge ;(
