find in admincp/global.php

else if ($_POST['do'] AND ADMINHASH != $vbulletin->GPC['adminhash']) 
{ 
    echo 'Admin Hash Mismatch'; 
    exit; 
}

change to

/* 
else if ($_POST['do'] AND ADMINHASH != $vbulletin->GPC['adminhash']) 
{ 
    echo 'Admin Hash Mismatch'; 
    exit; 
} 
*/

when youve done just change it back again
If you need to change the settings again you will have to edit the file again

that works if you set it in the global settings of wmail

eg you want all the members to use @domain.tld email addresses

you would set mail.domain.tld as your pop3 server with no override

with 8 email addys not a good idea although if you want only staff to use it then you will have to give them an email addy
