Check this code please...

Okay.. the previous post edited.

Aiii... what if you get rid of the quote marks from :

$to1 = "$Email";

... if no luck... then try echoing out $Email, and check you don't have any weird characters, perhaps either side of the string.

To top, you should really be checking mail values.... here, you can have my little routine :

PHP Code:

if(strstr($emailAddress,'@') && strstr($emailAddress,'.')) {
  if ($emaildomain=substr(strstr($emailAddress,"@"),1)) {
    $tmp = getmxrr($emaildomain, $mxs);
    if (!$mxs[0]) {
      // mail domain doesn't exist... so output error here
    } else {
      // domain exists... you can accept the address
  }
} else {
  // the supplied address is invalid...
  // ie, it doesn't contain a @ (at symbol) or a . (full stop)
} 


... if i'm too late, or have been no help, then forgive.... i'm just mental.
