Changing the mail spool directory

Hi,


I'm completely baffled here and would really like to start 2005 with a
working e-mail system <lol>!

I am running Linux From Scratch and am using Postfix as my MTA. I want
to be able to access my mail using IMAP from both Outlook Express
(yuk!) and Squirrelmail. I would also like to be able to access mail
from the command-line, so I want a solution that doesn't do anything
too clever in the way it stores it's mail!


Currently, I use MUTT on the command-line and this works well. I have
UW imapd set up, but this was only "seeing" mail that had already been
read by MUTT (and hence moved to the home directory from
/var/mail/<user>). I realised that UW imapd expected new mail to be in
/var/spool/mail/<user> so I moved the directory and changed the setting
in main.cf.


Now for the problem. postconf tells me that my mail_spool_directory is
/var/spool/mail, but if I send a test mail to my system, it gets
bounced with the following error message:

The Postfix program

: can't create user output file. Command output:
procmail: Couldn't create "/var/mail/paul"

what gives? Can anyone suggest where I should go from here, please?
TIA

Paul
