All the e-mail validation functions will return info@info.info as an invalid e-mail address.
All of the functions check the number of characters after the last dot, and it can be 2 or 3 and
here it's 4 :)
Here's the tweaked function:
function is_validEmail($email) {
if (eregi("^[0-9a-z]([-_.]?[0-9a-z])*@[0-9a-z]([-.]?[0-9a-z])*\\.[a-z]{2,4}$",
$email, $check)) {
if ( getmxrr(substr(strstr($check[0], '@'), 1), $validate_email_temp) ) {
return TRUE;
}
// THIS WILL CATCH DNSs THAT ARE NOT MX.
if(checkdnsrr(substr(strstr($check[0], '@'), 1),"ANY")){
return TRUE;
}
}
return FALSE;
}
or the Windows version (where DNS functions don't work):
function is_validEmail($email) {
if (eregi("^[0-9a-z]([-_.]?[0-9a-z])*@[0-9a-z]([-.]?[0-9a-z])*\\.[a-z]{2,4}$",
$email, $check))
return TRUE;
return FALSE;
}
Cheers everybody!
Saveli.
