*NOTE*

This hack will only check the email domain of the users' email addresses, since it is not really possible to verify each and every email address. If you would like to actually check every one of your users' email addresses, then you'll have to send an email out to them, and see which ones bounce.

This version of this hack only displays the users that have invalid email addresses. Use this for quickly checking which users have invalid/non-existent/no email addresses, instead of version below.

This version of this hack is the same as the above, but it will display ... valid or ... INVALID when checking your members. It's a good idea to use this if you're not sure if the hack locks up after processing a large number of users (so basically, use this version if you have a large number of users).

how long does this process take? I clicked the begin process 10 minutes ago and its still chuggin away....

It depends how many users you have on your forums..
Mine took about 25 seconds with a 512k connection, and I have 176 active members and 253 in total.

Just leave it and wait until it finishes; anyways, it shouldn't take TOO long, although I haven't yet tested it myself on a fairly large board yet.

I've done similar to this, but instead applied it to the 'user prune' page, so you can mass erase those users if need be.

It's funny to see how many users under 'waiting for email verification' have invalid emails.

To do as I've done, just find in admin/user.php:

PHP Code:

echo "<tr class='".getrowbg()."' align='center'>
                <td><font size='1'><b>ID</b></font></td>
                <td><font size='1'><b>Username</b></font></td>
                <td><font size='1'><b>Email</b></font></td>
                <td><font size='1'><b>Posts</b></font></td>
                <td><font size='1'><b>Last Visit</b></font></td>
                <td><font size='1'><b>Join Date</b></font></td>
                <td><input type='checkbox' name='allbox' onclick='CheckAll()' title='select/deselect all' checked></td>
            </tr>\n";
            while ($user = $DB_site->fetch_array($users)) { 


And below it place:

PHP Code:

list($username, $maildomain) = split("@", $user['email']);
                      if (!checkdnsrr($maildomain, "MX"))
                   {
                       $user[email] .= "</a> <font color=\"red\">[<b>invalid email</b>]</font>";
                   } 


It would also make sense to apply this MX lookup to the registration page, to kill the problem at the root.

Well, then you might as well just enable the email verification upon registration
