Subject: Snarfing /var/spool/mail/ into ~/INBOX for POP users

drivers.txt says:
| If "black box mode" is not in effect, messages are automatically
| transferred ("snarfed") from the spool directory to an INBOX in mbox,
| mx, mbx, tenex, and mtx formats.
This works fine for imapd, but ipop3d doesn't pick up new mail. Is this
normal behavior, or did I break something?
I have UW-IMAP 4.6-release patched to use hashed mbx-format folders for
INBOX. My patches follow (they're small).
Forking off a tmail for every incoming message would be a major loss from
postfix's own delivery agent.
P.S. I've got IMAP referrals happening, but since neither Netscape nor
Outlook seem to notice, they're not doing anything for me.
