How to configure mail (mailutils) to use Maildir schema by default?
Solution 1:
Afaik "mail" utility checks mails at the location given with the MAIL environment variable. Try this command: MAIL=/home/USER/Maildir/ mail (for sure, replace USER with something meaningful & valid). If that works, it seems that you should set MAIL variable you can do it in your bash profile / rc file for example. You can check the content of your current MAIL variable with: echo $MAIL
Solution 2:
To fetch mail from users home directory, use mail with -f option
mail -f /home/USER/Maildir/
