[Mimedefang] Directories under MIMEDefang

[Mathew Thomas]

Hi,

I have noticed that mimedefang is creating several directories in MIMEDefang directory with the name similar to "qdir-2003-05-27-10.57.20-001" and creating several files as below . What are these directories? Can I delete these directories? 

/var/spool/MIMEDefang/qdir-2003-05-27-10.57.20-001
%ls -al
total 24
