This is the relevant piece of code from a system not too far away from
me... It is in the WorkArea.pm file... The slightly different names
are... normal... Look at ConfigDefs.pl to see how they are translated
(and for defaults) from the "Quarantine Permissions" ->
quarantinepermissions -> quarantineperms ... Anyway, here is the
snippet:
----
  my($perms, $dirumask, $fileumask);

  $perms = MailScanner::Config::Value('workperms') || '0600';

  $perms = sprintf "0%lo", $perms unless $perms =~ /^0/; # Make it octal

  $dirumask = $perms;

  $dirumask =~ s/[1-7]/$&|1/ge; # If they want r or w give them x too

  $this->{dirumask}  = oct($dirumask) ^ 0777;

  $fileumask = $perms;

  $this->{fileumask} = oct($fileumask) ^ 0777;
----
Pretty self-explanatory (well-commented code, and sanely written
IMO... As always with Jules:).
With a "mask" of 0660, this will translate to 0770 for directories...
At least if I'm reading it right:-). My system agrees with me:-):-).
