I you've upgraded to the latest version and see taint errors in file.pm 
then edit the file PFDiskstore.pm at the line ~629:

sub CopyEntireMessage {
   my $this = shift;
   my($message, $targetdir, $targetfile, $uid, $gid, $changeowner) = @_;

   #print STDERR "Copying to $targetdir $targetfile\n";
   if (MailScanner::Config::Value('storeentireasdfqf')) {

change to:

sub CopyEntireMessage {
   my $this = shift;
   my($message, $targetdir, $targetfile, $uid, $gid, $changeowner) = @_;

   $targetfile =~/([\w\d]{10}.[\w\d]{5})/;
   $targetfile = $1;

   #print STDERR "Copying to $targetdir $targetfile\n";
   if (MailScanner::Config::Value('storeentireasdfqf')) {

This way you don't have to disable the taint mode which is a bit safer. 
(I even created a debian package with this fix if you're interested)
