I've always used $QueueID as unique BUT I'm sure it has some possibility of 
not being random especially if you use more than one server.  For Quarantine 
messages, I believe get_quarantine_dir() will give you a 100% guaranteed 
unique dir for a single quarantine location though this assumes that MD has 
some code to handle collisions on the creation of these directories.  From 
checking it looks like it does it with a timestamp and a 1000 counter loop.
