[Dovecot] Newbie Q: Setting up under linux: Spool directory.

I am trying to set up dovecot under linux. (RH9 if it matters). I'm having trouble having it find the mail that is already delivered.

What I would like is that mail is delivered by fetch mail to /var/spool/mail/mclay (that me) then have dovecot find it. I'm sure that I have not set the dovecot.conf file correctly. The documentation is unclear as to what "mbox" is and "INBOX" is.

I have tried having default_mail_env unset and with the following:

default_mail_env = mbox:/var/spool/mail/%u:INBOX=:/home/%u/Maildir

What I get when I talk to it directly is:

$ telnet localhost imap Trying 127.0.0.1... Connected to localhost Escape character is '^]'.

• OK dovecot ready. A00002 LOGIN mclay "xxxxxx" A00002 OK Logged in. A00003 SELECT INBOX A00003 NO Internal error [2004-04-26 12:56:03]

So could a kind sole point me in the right direction?

Thanks
