Inexplicable missing permissions issue

[Nelson Crosby]

Greetings all.

I've been having great difficulty getting Dovecot working. I'm getting
stuck with using mbox directories outside of /home. Dovecot keeps giving
me this message:

    imap(ncrosby): Namespace '': stat(/var/logmail/mbox/ncrosby) failed: Permis
    sion denied (euid=1001(ncrosby) egid=1001(ncrosby) missing +w perm: /var/lo
    gmail/mbox/ncrosby stat(/var/logmail/mbox/ncrosby) failed: Permission denie
    d, dir owned by 0:0 mode=0755) in=0 out=340

I've tried letting Dovecot create this directory, I've tried creating this
directory manually and giving it any permission I can think of, I've tried
playing about with the permissions throughout the entire /var/logmail tree,
but to no avail.

Below is my setup. I appreciate any input.

Here's `tree -apug /var/logmail`:

    /var/logmail
    ├── [drwx------ root     root    ]  lost+found
    ├── [drwxr-xr-x root     root    ]  mbox
    └── [drwxrwxr-x root     mail    ]  spool
        ├── [-rw-rw---- fedora   mail    ]  fedora
        └── [-rw-rw---- ncrosby  mail    ]  ncrosby

    3 directories, 2 files

And permissions for `/var/logmail` itself:

    drwxr-xr-x.  5 root root  4096 Sep 19 01:52 .

And now `doveconf -n`:

    # 2.2.31 (65cde28): /etc/dovecot/dovecot.conf
    # OS: Linux 4.11.8-300.fc26.x86_64 x86_64 Fedora release 26
(Twenty Six) ext4
    disable_plaintext_auth = no
    mail_location = mbox:/var/logmail/mbox/%n:INBOX=/var/logmail/spool/%n
    mbox_write_locks = fcntl
    namespace inbox {
      inbox = yes
      location =
      mailbox Drafts {
        special_use = \Drafts
      }
      mailbox Junk {
        special_use = \Junk
      }
      mailbox Sent {
        special_use = \Sent
      }
      mailbox "Sent Messages" {
        special_use = \Sent
      }
      mailbox Trash {
        special_use = \Trash
      }
      prefix =
    }
    passdb {
      args = dovecot
      driver = pam
    }
    service auth {
      unix_listener /var/spool/postfix/private/auth {
        group = postfix
        mode = 0666
        user = postfix
      }
    }
    ssl = no
    ssl_cert = </etc/pki/dovecot/certs/dovecot.pem
    ssl_cipher_list = PROFILE=SYSTEM
    ssl_key =  # hidden, use -P to show it
    userdb {
      driver = passwd
    }
