I just deployed an exim server with the exiscan patch, and I also
noticed that my /var/spool/exim/scan directory was filling up with
undeleted directories. I hadn't yet realised what was causing that,
until I saw this message, and then I went and looked, and sure enough,
all the directories left lying around contained messages that had
ms/tnef attachments. My directory had grown to 1.4 GB in just 2 days!
Maybe Tom can shed some light on this. There must be a missing unlink
or something missing in the code which handles tnef attachments.
