Function validEmail($emailaddress)
{
// Decides if the email address is valid. Checks syntax and DNS
// records, for total smartass value. Returns "valid", "invalid-mx"
// or "invalid-form".
if
(eregi("^[0-9a-z]([-_.]?[0-9a-z])*@[0-9a-z]([-.]?[0-9a-z])*\\.[a-z]{2,3}$",
$emailaddress, $check))
{
if ( checkdnsrr(substr(strstr($check[0], '@'), 1), "ANY") )
{ return "valid"; }
else
{ return "invalid-mx"; }
}
else
{
return "invalid-form";
}
}
If it gets through the first match with ".om", it won't get through the
checkdnsrr().
