The check to see if they are the same needs to be outside of the checks
for being blank. If they are both not blank, you will never get to the
last check. You could check for both in the first if, then do the
comparison. Something like (untested):
 
if (!trim($email1) || !trim($email2)) {
  echo "<BR>El <B>E-mail</B> es requerido en ambos campos.";
  $errors++;
} elseif ($email1 != $email2) {
  echo "<BR>Las <B>direcciones de E-mail</B> no concuerdan.";
  $errors++;
}
