Does this mean that if users never check the folder, the index file will
grow indefinitely, even though I delete old messages every night?
This is a spam folder, so it is not unlikely that it could remain unread.

Just to be sure: this means that deliver will clean up the index as soon
as the next spam arrives? That would be okay, even though some users are
still on procmail.
Then it seems to me that the expire-tool does not give me much
advantage, and adds the burden of an extra database. I guess it is most
useful if you have it watch folders that are not used every day?
