thanks cant figure out problem.

there can multitude of reasons... on windows or linux server?

check phpinfo see if sendmail correctly configured (sendmail_path).

if correctly configured, check why emails not being sent in smtp server log messages, check more details: http://pt.php.net/manual/en/function.mail.php#101588

if don't have sendmail correctly configured, can still use account have in smtp server send emails. should use php lib facilitate work, example, check this: http://swiftmailer.org/

also, test php code send email , see if works:

mail('youremail@example.com', 'my subject', 'test message');
