+## Migracion de mdbox a maildir
+
+Decidí migrar porque el sis storage está deprecado. Adicionalmente al intentar sincronizar / hacer backup de la mdbox aparecen errores de integridad, seguramente por este storage

+```
+docker compose stop dovecot
+docker run --rm -ti -v mail_mail:/vmail eumau/dovecot:4 bash
+doveadm backup -f -u mauro@mau.ro Maildir:~/maildir
+### repetir para todos los usuarios

+### Actualizar imagen a 4-to-5
+docker compose up -d
+### Ahora ya deberíamos tener maildir sin attachments externos
