If I set the mailbox location to point to the file, I get another error
about how the root directory can't be a file. The exact error is:
Jun 16 08:21:57 eeebox dovecot: master: Dovecot v2.0.beta6 starting up
Jun 16 08:22:07 eeebox dovecot: pop3-login: Login: user=<cmcmanis>,
method=PLAIN, rip=66.125.189.27, lip=66.125.189.30, mpid=80225, TLS
Jun 16 08:22:07 eeebox dovecot: pop3(cmcmanis): Error: user cmcmanis:
Initialization failed: Initializing mail storage from mail_location setting
failed: mbox: mbox root directory can't be a file: /home/cmcmanis/Mailbox (
http://wiki.dovecot.org/MailLocation/Mbox)
Jun 16 08:22:07 eeebox dovecot: pop3(cmcmanis): Error: Invalid user
settings. Refer to server log for more information.

Now it strikes me that this message indicates that Dovecot is confused about
how mail is delivered on my system and is looking for a Maildir
implementation when I"m using single files. And yet I can't find a variable
in any of the various configuration files which can set for sure the mbox
"mode".

Dovecot should have logged, where it is looking for mails. If you can't

I have logging-conf set to both

auth_debug = yes
auth_verbose = yes

But it doesn't say anything else than what you see above.
