Orphaned processing directory

[Hancock, Scott]

I have a directory containing 60 files in /var/spool/MailScanner/input

The directory is 6 days old at this point.

How can I tell MailScanner to process these files?  

Or can I assume these files have already been processed and the
directory clean up was missed?

I see in the mail log the incoming event but not the delivery.  I think
exim would tag another msg ID after MailScanner processing anyway?

Thanks for any help
