Error send gmail mail

If it is timing out, the problem is due to your host not supporting ipv6 addresses. The plugin needs to make a special case for this problem. The specific changes to the code (in swpsmtp_test_mail & swpsmtp_init_smtp) are these two lines added after $mail->Host has been set:

$mail->Host = gethostbyname($mail->Host); // converts name to ipv4 address
$mail->SMTPOptions = array('ssl' => array('verify_peer_name' => false));

The first line forces the host to be an ipv4 address. The second line allows the use if just an ip address instead of a domain name for authentication.
