I am trying to set up an IMAP server on my basic Centos 7 mail server. I have postfix MTA set up and delivering mails to the following directory (I have no reason to change this to use the $HOME directory):
root@mail3:/var/spool/mail
# ls -ltrh
total 12K
-rw-rw----. 1 rpc mail 0 Feb 29 2020 rpc
-rw-rw----. 1 centos mail 0 Feb 3 19:39 centos
-rw-rw----. 1 bruce mail 0 Feb 3 19:47 bruce
-rw-rw----. 1 navid mail 0 Feb 3 19:47 navid
-rw-rw----. 1 mcchen mail 0 Feb 3 19:47 mcchen
-rw-rw----. 1 rab mail 9.0K Feb 4 16:44 rab
mailx on the server indicates that mails are stored in /var/spool/mail/%n:
[rab@mail3 ~]$ mailx
Heirloom Mail version 12.5 7/5/10. Type ? for help.
"/var/spool/mail/rab": 5 messages 3 unread

I have the following configuration (from default) set in dovecot.conf and 10-mail.conf:
# vi dovecot.conf
protocols = imap
login_greeting = Dovecot ready.
listen = *, ::
root@mail3:/etc/dovecot/conf.d
# vi 10-mail.conf
mail_location = maildir:/var/spool/mail/
I also added global write permissions on /var/spool/mail and mailbox files as I then had an error related to permissions.
I now find that I can login via IMAP and SELECT INBOX, but it produces an empty mailbox, suggesting that it is not picking up my mailbox file in /var/spool/mail/rab
# telnet 0 143
Trying 0.0.0.0...

Can anyone point me in the right direction with this?
