As a general rule, it is a good idea to have separate Mailformat
directory (such as Maildir or Mail) under mail_home which contains only
your Maildir, sdbox, mdbox whatever format files only, and keep control
and index *OUT* of this directory. Same goes for sieve. This is because,
as seen above, Maildir contents can be mistakenly interpreted as mail
folders, causing problems.

So avoid this:

mail_home=/var/mail/%u
mail_location=/var/mail/%u

instead use

mail_home=/var/mail/%u
mail_location=Maildir:~/Maildir
