>Description:
In FreeBSD 3.0-RELEASE ( and lower versions ! )
if environment variable MAIL exists,
then "/usr/bin/mail -u user" always open mailbox ${MAIL}
In FreeBSD 3.0 by default exists $MAIL ( via /etc/login.conf )
"/usr/bin/mail -u user" under root always open MAIL=/var/mail/root,
though "/usr/bin/mail -f /var/mail/user" worked fine
Also in "man mail" we reading:
-u Is equivalent to:
mail -f /var/mail/user
I look at code of mail program and found that this is not true,
if exists environment variable $MAIL
>How-To-Repeat:
Under root and /bin/sh type:
MAIL=/var/mail/root mail -u user
where user - some user in your system
Always opened /var/mail/root file !
