What are common issues when using phpMail to send emails with OpenSSL?

Common issues when using phpMail to send emails with OpenSSL include SSL certificate verification errors and connection timeouts. To solve these issues, you can disable SSL certificate verification or increase the connection timeout value in your PHP code. 

// Disable SSL certificate verification
$transport = new Swift_SmtpTransport('smtp.example.com', 587, 'tls');
$transport->setStreamOptions(['ssl' => ['verify_peer' => false, 'verify_peer_name' => false]]);

// Increase connection timeout value
$transport = new Swift_SmtpTransport('smtp.example.com', 587, 'tls');
$transport->setTimeout(30); // Set timeout to 30 seconds
