Zend Mail Protocol Exception: Could not open socket
« on: June 19, 2019, 10:10:33 PM »
My app require a library from Zend Mail but when try to send the mail get the following error:

Zend Mail Protocol Exception: Could not open socket

The code related to this message:

Code: [Select]
    protected function _connect($remote)
    {
        $errorNum = 0;
        $errorStr = '';

        // open connection
        $this->_socket = @stream_socket_client($remote, $errorNum, $errorStr, self::TIMEOUT_CONNECTION);

        if ($this->_socket === false) {
            if ($errorNum == 0) {
                $errorStr = 'Could not open socket';
            }
            /**
             * @see Zend_Mail_Protocol_Exception
             */
            require_once 'Zend/Mail/Protocol/Exception.php';
            throw new Zend_Mail_Protocol_Exception($errorStr);
        }

        if (($result = $this->_setStreamTimeout(self::TIMEOUT_CONNECTION)) === false) {
            /**
             * @see Zend_Mail_Protocol_Exception
             */
            require_once 'Zend/Mail/Protocol/Exception.php';
            throw new Zend_Mail_Protocol_Exception('Could not set stream timeout');
        }

        return $result;
    }

My Zend Mail cfg:

Code: [Select]
email.host                          = myhost.mydomain.com
email.smtp_auth                 = true
email.username                  = mail@mydomain.com
email.password                   = mypasswd
email.smtpport                   = 465
email.secure                       = ssl
email.ack                           = false
email.use_local_sendmail    = false

Transport layer is okay:
Code: [Select]
[root@central /]# php -r 'print_r(stream_get_transports());'
Array
(
    [0] => tcp
    [1] => udp
    [2] => unix
    [3] => udg
    [4] => ssl
    [5] => sslv3
    [6] => sslv2
    [7] => tls
    [8] => tlsv1.0
    [9] => tlsv1.1
    [10] => tlsv1.2
)

Module OpenSSL is working:
Code: [Select]
[root@central /]# php -m
