php-swiftmailerHow to ignore a certificate when using Swiftmailer?

Swiftmailer provides a way to ignore a certificate when using it. To do this, you need to set the stream_options parameter to ['ssl' => ['verify_peer' => false, 'verify_peer_name' => false]] when creating the transport instance.

Example code

$transport = (new Swift_SmtpTransport('smtp.example.org', 465, 'ssl'))
    ->setStreamOptions(['ssl' => ['verify_peer' => false, 'verify_peer_name' => false]]);

Code explanation

• Swift_SmtpTransport: This is the class used to create the transport instance.
• smtp.example.org: This is the hostname of the SMTP server.
• 465: This is the port used for the SMTP server.
• ssl: This is the encryption protocol used for the SMTP server.
• setStreamOptions: This is the method used to set the stream_options parameter.
• ['ssl' => ['verify_peer' => false, 'verify_peer_name' => false]]: This is the value of the stream_options parameter, which is used to ignore the certificate.
