Messages enter and get processed by procmail, which does (essentially) two things:

1. passes them to ifile, which classifies and adds a header 

  X-Ifile-Hint: FOLDER

2. puts the message into folder FOLDER

Every night, a cron job scans through all folders and looks for messages
which have been put into the wrong folder (X-Ifile-Hint says FOLDER_1
but the email is in FOLDER_2).  It tells ifile to delete the message
from FOLDER_1 and add to FOLDER_2.  Thus, if FOLDER_2 is new, ifile
learns about a new category.

Once ifile knows enough about FOLDER_2 to correctly put emails into it,
it will start suggesting FOLDER_2 as a category for new emails, and so
procmail will immediately filter straight into FOLDER_2, even without
touching config files.  This "correction" when you add a new category is
quicker if you have a seed of messages to start the new folder with, but
it works either way.
