Title: Update framework/validators/CEmailValidator.php

If fsockopen error "Connection refused" (error code: 61) is reached, yii hangs with uncatched 500 error code.

Output html code:
```html

PHP Error [2]

fsockopen() [function.fsockopen]: unable to connect to mail.somedomain.com:25 (Connection refused)

```
