Hi!
Machine in question is Debian slink install from 1999, upgraded to
potato in 2000, and recently upgraded to woody. Now see:
[2/502]haber@paola:~$ ssh q
Linux q 2.4.19-coreserver #1 SMP Mon Aug 19 14:33:07 UTC 2002 i586 unknown
[1/500]mh@q:~$ echo $MAIL
~/below. ~/directory ~/.mail/mailbox
[2/500]mh@q:~$ grep MAIL /etc/login.defs
# Three items must be defined: MAIL_DIR, ENV_SUPATH, and ENV_PATH.
# home directory. If you _do_ define both, MAIL_DIR takes precedence.
# QMAIL_DIR is for Qmail (or any maildir-compatible MTA, such as Exim or
# Essentially, MAIL_DIR defines the $MAIL environmental variable
# (for mbox use) by appending the username to MAIL_DIR as defined
# below. MAIL_FILE defines the $MA IL environment variable as the
# directory before $MAIL_FILE, and QMAIL_DIR defines the MAIL
# obtained by prepending the user home directory before $QMAIL_DIR.
# NOTE: This is used to setup your MAIL environment variable, and also
# in determining the $MAIL environmental variable.
#QMAIL_DIR Maildir/
#MAIL_DIR /var/mail
MAIL_FILE .mail/mailbox
#MAIL_CHECK_ENAB
[3/501]mh@q:~$ logout
Connection to q.bofh.de closed.
Looks like the code that builds the MAIL environment variable does
indeed care about comment lines, using the second word in every line
containing the string MAIL_FILE to build the string assigned to the
environment variable MAIL.
For reference, with a modified /etc/login.defs - two strategically
placed spaces:
[3/502]haber@paola:~$ ssh q
Linux q 2.4.19-coreserver #1 SMP Mon Aug 19 14:33:07 UTC 2002 i586 unknown
[1/500]mh@q:~$ echo $MAIL
~/.mail/mailbox
[2/501]mh@q:~$ grep MAIL /etc/login.defs
# Three items must be defined: MAIL_DIR, ENV_SUPATH, and ENV_PATH.
# home directory. If you _do_ define both, MAIL_DIR takes precedence.
# QMAIL_DIR is for Qmail (or any maildir-compatible MTA, such as Exim or
# Essentially, MAIL_DIR defines the $MAIL environmental variable
# (for mbox use) by appending the username to MAIL_DIR as defined
# below. MAIL_ FILE defines the $MAIL environment variable as the
# directory before $MAIL_ FILE, and QMAIL_DIR defines the MAIL
# obtained by prepending the user home directory before $QMAIL_DIR.
# NOTE: This is used to setup your MAIL environment variable, and also
# in determining the $MAIL environmental variable.
#QMAIL_DIR Maildir/
#MAIL_DIR /var/mail
MAIL_FILE .mail/mailbox
#MAIL_CHECK_ENAB
[3/502]mh@q:~$ exit
logout
Connection to q.bofh.de closed.
[4/502]haber@paola:~$
This time, $MAIL is OK.
Please look into this really weird behavior.
On a fresh woody install, or on a potato installed, woody updated
machine, the setting of MAIL_FILE seems to be ignored, MAIL pointing
to /var/mail/$USER regardless of the settings in login.defs.
Greetings
Marc
