I use Gmail SMTP to send email from a web application that I wrote using CodeIgniter with PHP 5.3 without problems until recently. This is a piece of code:
$config['protocol'] = 'smtp';
$config['smtp_host'] = $this->smtp_host;
$config['smtp_port'] = $this->smtp_port;
$config['smtp_user'] = $this->smtp_username;
$config['smtp_pass'] = $this->smtp_password;
$config['mailtype'] = $this->email_type;
$config['newline'] = "\r\n";
$this->load->library('email', $config);
$this->email->from($email_sender, $email_sender_name);
$this->email->to($email_to);
$this->email->subject($message_subject);
$this->email->message($message_content);
$result = $this->email->send();
When I use "ssl://smtp.gmail.com"as a host and 465as a port, I got this error in the log:

I don't know if this is related, but before I updated my PHP to PHP 5.3, the same code worked fine. If these are problems with a firewall or Internet connection, I can still send an email using gmail smtp to Thunderbird.
After I look at different forums, I have tips for this test:
$ openssl s_client -starttls smtp -crlf -connect smtp.gmail.com:587

when using the same tool to test the connection sslgive me a timeout:
$ openssl s_client -ssl2 -crlf -connect smtp.gmail.com:465
connect: Connection timed out
