Why not leave the sieve script set to deliver into a mailbox called 'sent-active' all the time, then simply have the perl script rename that to yesterday's date and recreate the active mailbox again. You then do not need to edit the sieve script each day. The only problem with this is a possible race condition in which a message delivery to the mailbox is attempted between the rename and re-create actions. An alternative might be to create yesterday's mailbox and then copy all messages from the active one into that and expunge those. That way the active mailbox is around all the time avoiding the race. However, that requires a lot more work on the IMAP side as you have to select (open) the mailbox to do the copying.
