I think most people scanning their mail do so before it is stored in the 
filesystem.

How far should the server go assuming it knows the reason why some 
unexpected condition exists?  Should it happily ignore a missing 
/etc/cyrus.conf and assume default settings?  Should it assume /var/imap 
ran out of disk space because there were log files it should silently 
clean up for you?

I imagine it wouldn't be very difficult to hack the source so that 
whenever it tried to open a message file that didn't exist, it could 
create a message that says it was removed by virus scanning and then 
open that file, but that would have to be something you want to run -- I 
wouldn't want that in the version I was running and I doubt such a hack 
would get accepted into the codebase.
