Hi Mark,
I don't know shell scripting, but I put together a PHP script for you.
It loops through the directory, turns the directory name into the user
id, gets the owners userid and does the compare. Doesn't check things
starting with a ".".
Put it into a file on the server and run "php FILENAME" and wait for the
answer.
<?php
// Path to check
$path = "/var/spool/mail";
// Get the directory listing
$dir = dir($path);
// Go through the directory
while(($entry = $dir->read()) != NULL){
if(substr($entry, 0, 1) != "."){ // Don't check hidden items
$owner = fileowner($path."/".$entry); // Get the owner
$id = `id -u $entry`; // Get the ID of the user whos mailbox this is
if($id != $owner){ // If the ID and owner don't match
echo "Directory: ".$entry."\n"; // Print it out for Mark to see
}
}
}
?>
I think the reason this could have happened is that permissions are set
as the ID of the user (not the username). When the user is deleted, the
permissions don't change ID. When a new user is created, if they assume
the ID of the old person they also get ownership of what they had.
