It works for me...if the user is in /etc/passwd...
Code:
$
$ ABC=mail
$ grep mail /etc/passwd
mail:x:8:12:mail:/var/spool/mail:/sbin/nologin
mailnull:x:47:47::/var/spool/mqueue:/sbin/nologin
$ cd ~${ABC}
$ pwd
/var/spool/mail
$
$ ABC=fubar
$ cd ~${ABC}
ksh: cd: ~fubar: [No such file or directory]
$

conflict

CONFLICT(8)							     [nmh-1.5]							       CONFLICT(8)

NAME

       conflict - search for alias/password conflicts

SYNOPSIS

       /usr/lib/mh/conflict [-search directory] [-mail name] [-version] [-help] [aliasfiles ...]

DESCRIPTION

       Conflict is a program that checks to see if the interface between nmh and the transport system is in good shape

       Conflict also checks for maildrops in /var/mail which do not belong to a valid user.  It assumes that no user name will start with `.', and
       thus ignores files in /var/mail which begin with `.'.  It also checks for entries in the group(5) file which do not belong to a valid user,
       and for users who do not have a valid group number.  In addition duplicate users and groups are noted.

       If  the	-mail  name  switch is used, then the results will be sent to the specified name.  Otherwise, the results are sent to the standard
       output.

       The -search directory switch can be used to search directories other than /var/mail and to report  anomalies  in  those	directories.   The
       -search directory switch can appear more than one time in an invocation to conflict.

       Conflict should be run under cron(8), or whenever system accounting takes place.
