I guess it can't send to an invalid email adress You should use the check_valid_email() function in include/email.php.

Follow these easy instructions:
----
? At the top of AP_Broadcast_Email, right after this code:

define('PUN_PLUGIN_LOADED', 1);

? Add this:

include PUN_ROOT."include/email.php";

? Then find this code:

while($row = $db->fetch_assoc($result))
       {
           $addresses[$row['username']] = $row['email'];
       }

? Replace it with this code:

       while($row = $db->fetch_assoc($result))
       {
        if(!is_valid_email($row['email']))
            continue;
           $addresses[$row['username']] = $row['email'];
       }

I think that should do the trick

Odd... make sure your SMTP settings are correct.

Myeah, but what if he just converted from another software that doesn't check it? You never know.

Notice that misc.php doesn't check if an email address is valid. If it's in the database, it should be properly checked. If it wasn't in the example you gave, the convertor messed up
