Puedes verificar si estás ejecutando la versión antigua de `mail-receiver` de la siguiente manera.

```plaintext
docker exec mail-receiver bash -c "cat /etc/issue|grep Alpine"

```

Si es Alpine, es la versión antigua.

```plaintext
docker exec mail-receiver bash -c "cat /etc/issue|grep 'Debian GNU/Linux 11'"

```

Si es Debian, es la versión nueva.
