Not sending Feedback Form

[yiannos]

Help!!!

I have written the following php for a feedback form. the problem i am facing is the following:
When the
$mailto = 'yiannos@mydomain.com' ;
is written the script works perfect and the email is send.

When the
$mailto = 'yiannos@mydomain.com.cy' ;
is written and no other changes in the script the email is NOT send. the only difference is that my domain has a .cy at the end.

Please, Any help will be appreciated

My Code Follows
