Running Ubuntu server 18.04 and have installed PostFix and mailutils.
I have sent some test emails to postfix and they are stored in a plain text file at
/var/mail named as the recipient alias. When I use the
Cannot open mailbox /home/user/Maildir/: Is a directory No mail for user You have mail in /home/user/Maildir/
The folder is empty and the reply is contradicting. How do I set this up properly? It got changed when I was blindly following other directions and now I'm lost as it's not default anymore.
