As an alternative method, you can use the Code Snippets plugin to insert your codes into WordPress.

Copy the PHP code from the below box and paste it at the end of the functions.php file.

add_action( 'phpmailer_init', function ( $phpmailer ) {
$Outgoing_Server = '';
$Port = '25';
$email = '';
$password = '123456';
$site_name = 'Redpishi';
$phpmailer->Host       = $Outgoing_Server;
$phpmailer->Port       = $Port;
$phpmailer->SMTPSecure = '';
$phpmailer->SMTPAuth   = true;
$phpmailer->Username   = $email;
$phpmailer->Password   = $password;
$phpmailer->From       = $email;
$phpmailer->FromName   = $site_name;
$phpmailer->addReplyTo($email, $site_name);
$phpmailer->SMTPOptions = array(
    'ssl' => array(
        'verify_peer' => false,
        'verify_peer_name' => false,
        'allow_self_signed' => true
} );

add_action('wp_mail_failed', function ( $wp_error ){
	$timee = date("Y-m-d");	
	$emaill = array(
	"email_to" => $args["to"],
	"email_subject" => $args["subject"],
	"email_message" => $args["message"]
    $fn = ABSPATH . '/mail.log'; // say you've got a mail.log file in your server root
    $fp = fopen($fn, 'a');
	fputs($fp, "Mailer Error: " . serialize($wp_error).  " email: " . $emaill[1] . "  time -> " . $timee . "\n");	
}, 10, 1);

Step 4.Configure SMTP code

You can find the outgoing server in step 2.2.

$Outgoing_Server = '';

Don’t change the port unless you what you are doing.

$Port = '25';

Enter the email and password you created in step 1 here.

$email = '';
$password = '123456';

Write your site name here.

$site_name = 'Redpishi';

Step 4.Check the email sent.

Save the functions.php file and submit a contact form to make sure that the email is sent correctly.
