En primer lugar, hay uno muy similar.preguntaal mío. Soy consciente de ello, sin embargo, el método que presentaron las personas en este hilo desafortunadamente no funcionó de la misma manera esperada para mí que para ellos.
Por eso estoy creando una nueva pregunta.
He instalado un servidor de correo en un sistema Raspibian basado en Debian con Dovecot y Postfix.
Salida de apt list --installed | grep dovecot:
dovecot-core/stable,now 1:2.2.27-3+deb9u2 armhf [installed]
dovecot-imapd/stable,now 1:2.2.27-3+deb9u2 armhf [installed]

Salida deapt list --installed | grep postfix
postfix/stable,now 3.1.8-0+deb9u1 armhf [installed]
postfix-sqlite/stable,now 3.1.8-0+deb9u1 armhf [installed,automatic]
Ahora me enfrento al problema: puedo enviar correos electrónicos y, según los archivos, ~/Maildir/newtambién recibir correos electrónicos como con cualquier otro servidor de correo que funcione normalmente. Sin embargo, mi problema es que no recibo ningún correo electrónico en mi bandeja de entrada.
No sé en qué parte de la configuración de Dovecot y Postfix está mi error.
Esta es la salida de/etc/dovecot/conf.d/10-mail.conf

5 # Location for users' mailboxes. The default is empty, which means that Dovecot
6 # tries to find the mailboxes automatically. This won't work if the user
7 # doesn't yet have any mail, so you should explicitly tell Dovecot the full
8 # location.
9 #
10 # If you're using mbox, giving a path to the INBOX file (eg. /var/mail/%u)
11 # isn't enough. You'll also need to tell Dovecot where the other mailboxes are
12 # kept. This is called the "root mail directory", and it must be the first
13 # path given in the mail_location setting.
14 #
15 # There are a few special variables you can use, eg.:
16 #
17 # %u - username
18 # %n - user part in user@domain, same as %u if there's no domain
19 # %d - domain part in user@domain, empty if there's no domain
20 # %h - home directory

36 # are for user's personal mails. Shared namespaces are for accessing other
37 # users' mailboxes that have been shared. Public namespaces are for shared
38 # mailboxes that are managed by sysadmin. If you create any shared or public
39 # namespaces you'll typically want to enable ACL plugin also, otherwise all

Tienes:
mail_location = mbox:~/Maildir:INBOX=/var/mail/%u
Sin embargo, también escribe que los mensajes nuevos se escriben en ~/Maildir/new/, que es el formato Maildir, no mbox.
Cambie esa línea a
mail_location = maildir:~/Maildir
y deberías poder leer tus mensajes.
