[Mimedefang] Testing for the existence of a header

Carrying on from my original problems, I am now faced with something 
that so far I have not been able to solve.

I need to test for the existence of a Maildir folder. If they are less 
than 6 characters long they are space padded with leading spaces to 6 
(don't ask please).

Here is the code:

if (exists($Header{'x-strata-plan'})) {
       if(! exists($staff_codes{$Header{'x-strata-plan'}})) {
                # pad with spaces to left to at least 6 characters
          my $spno = $Header{'x-strata-plan'};
          my $pad_spno = sprintf("%6s", $spno);
          my $dirname = '"/home/plans/Maildir/.' . $pad_spno . '"';
          if  (! -d $dirname) {
             return action_bounce ("You entered $spno which is an 
invalid code. Folder name was $dirname");

I got the "staff_codes" thing working (thanks to previous assistance 
here) but when I test the folder part I get the following displayed:

Oct  2 13:24:12 sydsrv01 sendmail[7872]: m923OA78007872: Milter: data, 
reject=554 5.7.1 You entered 226 which is an invalid code. Folder name 
was "/home/plans/Maildir/.   226"

But the folder definitely exists. Is this something to do with the 
difference between ' and "?

If I copy the message portion and test it I get this:

[root at sydsrv01 mail]# ls -ld "/home/plans/Maildir/.   226"
drwxr-xr-x 2 root root 4096 Oct  2 12:47 /home/plans/Maildir/.   226

I get the same result if I use backslashes to escape the spaces instead 
of quoting them.
