SSL SMTP failed

[markopraakli]

After upgrading EspoCRM 4.3.1 to 4.5.0 then Outbound emails stopped working. Here are following logs when I'll push "Send Test Email" button:

[2017-03-21 08:14:16] Espo.WARNING: E_WARNING: stream_socket_client(): php_network_getaddresses: getaddrinfo failed: No address associated with hostname {"code":2,"message":"stream_socket_client(): php_network_getaddresses: getaddrinfo failed: No address associated with hostname","file":"/var/www/vhosts/xxx/vendor/zendframework/zend-mail/src/Protocol/AbstractProtocol.php","line":203,"context":{"remot e":"ssl://smtp.xxx.yy:465","errorNum":0,"errorStr":""}} []

And when I try to make new php fail for testing and it contains following code, then socket is working:

<?php
$h = stream_socket_client( 'ssl://smtp.xxx.yy:465', $errno, $errstr);
var_dump($h);
var_dump($errno);
var_dump($errstr);

DNS, hosts are correct. Any ideas?
