May be a firewall issue. However I'm pretty sure php-openssl doesn't installed/enabled on your OS. Under the hood Zend will call stream_socket_client() in order to connect to remote server. As sending email through gmail requires security layer (SSL/TLS), stream_socket_client() will require open ssl support (ssl://). So you must have ssl support on OS, check:

Or getting the list of supported socket transports:
