dovecot - Jul 2007 - Integrating dovecot 1.01 into CentOS-3.8 systemw with chroot passwd dirs?

Hello. I'm administrating a CentOS 3.8 linux system (RHEL3) and I just
replaced
the imap-2002d-12 package that came with the system, with a dovecot 1.01
package I obtained through the dovecot home page. The problem I have, is that
many of my POP3 users have jailed user accounts set up through wu-ftpd, where
the dir field is of the form /home/group/./pop/user, and wu-ftpd chroots them
from /home/group but then places them into their home directories, in this case
/home/group/pop/user. dovecot can't seem to locate their mail directory.

Can anyone offer any advice on this situation?

Please respond to my email address <og at digimark.net> if you could.

Here are some relevant stats:

example user: lda01
home directory (in /etc/passwd: /home/lda/./pop/lda01
mail folder directory: /home/lda/pop/lda01/mail
INBOX: /home/mail/lda01   (/var/mail, /var/spool/mail symlinked to /home/mail.)

Dovecot chroots the users as well then.

Change this to:

mail_location: mbox:~/mail:INBOX=~/%u

Does it work then?

Thanks for the reply; That's good news.

Wouldn't that parse to $HOME/$USER for each inbox? Currently
sendmail/procmail
delivers mail to /var/mail, which is symlinked to /home/mail in my system.
