Hello friends,
While i am trying to send mail from my site in a form field, following msg appears, please help me in this regard.

------------------------------------------------------------------------------------------
Warning: mail() [function.mail]: "sendmail_from" not set in php.ini or custom "From:" header missing in C:\wamp\www\Site\feedback.php on line 29
------------------------------------------------------------------------------------------

it seems there is a problem in your PHP installation ,what is your php version ??? , check if mail function is disabled in php.ini .
