I use the QuarantineSubdir value, not QueueID, sorry for confusion. I
played with both of them.

Okay, I understand. I found another way to trigger the external script
by iwatch just touch'ing a file from within mimedefang to a directory
which is watched by iwatch. This is quite fast and keeps the script
separate from mimedefang.
