I dont understand.. in my server I can run the form perfectly? but in the
client server not? appears this message:

 

Warning: mail() [ <http://www.consultapsico.com.ar/demo/function.mail>
function.mail]: "sendmail_from" not set in php.ini or custom "From:" header
missing in D:\Service\Sites\Consultapsico\www\demo\form.php on line 10
