Description of problem:
uw-imapd comes configured out of the RPMs shipped with both 7.2 and 7.3 to use
the user's home directory as the root of the user's mail folders. this causes OS
X mail.app and numerous webmail packages (most notably squirrelmail, which I
have noticed will be included in future redhat linux releases) to crash when
they attempt to access folders, as the ENTIRE contents of ~ attempts to go
across the IMAP connection. To fix this, I got the latest source for version
2002RC1, and modified src/osdep/unix/env_unix.c to point to ~/mail. I also took
the opportunity to set RestrictedBox = -1, which prevents access outside of the
mail directory and /var/spool/mail.

I am sure there is justification for having imap route to the home directory,
but I do not see it, as PINE stores things in ~/mail, and the rather popular OS
X mail.app goes absolutely insane when it tries to map the home directory.

Relevant excerpts from docs/CONFIG in the 2002RC1 source tree:

     Example 2: suppose you want to change c-client's idea of the
user's mailbox directory to be the "mail" subdirectory of the user's
home directory instead of the user's home directory.  You will want to
change variable mailsubdir, changing the line that reads:

static char *mailsubdir = NIL;  /* mail subdirectory name */
 to be:
static char *mailsubdir = "mail";/* mail subdirectory name */
     

...

     Example 5: suppose you want to disable non-namespace access to the
filesystem root and other users' names, but do not want to go to the
extreme of chroot() and you want to allow access to a traditional UNIX  
format INBOX in the mail spool directory.  You need to change variable 
restrictBox, changing the line which reads:

static short restrictBox = NIL; /* is a restricted box */
 to be:
static short restrictBox = -1;  /* is a restricted box */

How reproducible:
Always

Steps to Reproduce:
installed redhat 7.3 RPM release of imap-2001a-13. 

Actual Results:  Squirrelmail webmail crashed when attempting to access Folders
tab, first with an out of memory error, then with a timeout after max memory
size was increased in php.ini.
OS X mail.app attempted to download entire contents of ~ onto local machine,
with CPU at 100% and eventually hung.
