Answer 1

Apparently your PHP is not allowed to connect to the specified SMTP server. Did you properly configure your email-settings? (SMTP server, port, username, password etc).
A template for these settings is included with CakePHP in the file: app/Config/email.php.default (https://github.com/cakephp/cakephp/blob/2.2.7/app/Config/email.php.default)
You need to copy this file to app/Config/email.php and modify the settings for your environment.
After that, you'll have to specify the right configuration when sending emails
A more thorough explanation can be found in the manual:
http://book.cakephp.org/2.0/en/core-utility-libraries/email.html#configuration
update
Another option is that SELinux security-bits dissallow PHP/Apache to make network connections.
There are several security-bits, but this seems a likely candidate: httpd_can_network_connect .
You can temporarily allow PHP/Apache to make network connections using this:
setsebool httpd_can_network_connect
And make the setting 'permanent' using the -P parameter;
setsebool -P httpd_can_network_connect
For an overview of all SELibux booleans;

Answer 2

getsebool -a
Check httpd_can_network_connect
if off, set it to on
setsebool -P httpd_can_network_connect on
It works for me !!
