Checking for specific domain in email address?

Is your callback function getting called ?
Try placing an echo inside the function and see if it shows up, if not, the callback is not working.

Edit:

Your function needs to look something like:

Code:

function _valid_domain($email)
{
list($user, $domain) = explode('@', $email);
if ( $domain == 'mywebsite.com')
{
  return true;
} else {
  return false;
}
}
