las me dice el server(hosting) que coloque lo siguiente, alguien me puede decir donde va porfavor.... :

Le informamos que en nuestros servidores se encuentra habilitada la funcion mail
de PHP y la misma puede ser utilizada para el envio de correos desde los
formularios webs.
Ademas, debe tener en cuenta que en nuestro archivo de configuracion php.ini, no
se encuentra definida la variable sendmail_from y por lo tanto debera setearla
antes de realizar el envio.
Esto puede realizarce colocando la funcion
ini_set("sendmail_from", "email@midominio");
en la linea previa a la funcion mail()
REcuerde que email@midominio debe ser reemplazado por una cuenta de correos
existente en su panel de control.


gracias,
