Issue #3304449 by teknocat: Error sending e-mail from Sender Name <some@email.com>

      $from = $this->configFactory->get('system.site')->get('mail');

    }

    if (empty($from)) {

      $from = $message['from'];

    // The $from address might contain the "name" part. If it does, split it,

    // since PHPMailer expects $from to be the raw email address.

    $matches = [];

    if (preg_match('/^(.*)\s\<(.*)\>$/', $from, $matches)) {

      $from = $matches[2];

    }

    }

    // Updates $headers fields.

    $headers['sender'] = $from;
