Package swiftmailer/swiftmailer is abandoned, you should avoid using it. Use symfony/mailer instead

after long time i got the solution. That is :- This is just a package. You can avoid this things.. this is Nothing. Thanks

$ composer require “swiftmailer/swiftmailer:^6.0” Here is the simplest way to send emails with Swift Mailer:

require_once ‘/path/to/vendor/autoload.php’;

// Create the Transport

$transport = (new Swift_SmtpTransport(‘smtp.example.org’, 25))
->setUsername(‘your username’)
->setPassword(‘your password’)
;

// Create the Mailer using your created Transport $mailer = new Swift_Mailer($transport);

// Create a message

$message = (new Swift_Message(‘Wonderful Subject’))
->setFrom([‘john@doe.com’ => ‘John Doe’])
->setTo([‘receiver@domain.org’, ‘other@domain.org’ => ‘A name’])
->setBody(‘Here is the message itself’)
;

// Send the message

$result = $mailer->send($message);

You can also use Sendmail as a transport:

// Sendmail

$transport = new Swift_SendmailTransport(‘/usr/sbin/sendmail -bs’);
