How do I make SSH use the MAIL variable set by /etc/login.defs?
 

The problem I'm having is when a user logs in with SSH the $MAIL var = /var/mail/user! If I "su - user" MAIL is correctly set to ~user/mail


Next, I edited /etc/login.defs commenting out MAIL_DIR and setting the correct path for QMAIL_DIR & MAIL_FILE

exim is configured to deliver email to: ~user/mail -- I have verified that mail is correctly being delivered to ~user/mail/new

updated login & ssh in /etc/pam.d/ so that can correctly inform users of new mail upon login -- This works as expected

I finally managed to solve this by adding MAIL=~/mail to /etc/profile ... I'm not sure if that's the best way to solve the problem. mail now gives me the error ...which means mail isn't configured to support the Maildir format and I haven't been able to find any information on how to change that through searching. MUTT does work, though!
