Anothers problems after the installation :
- Dovecot is configured to listen on IPv4 and IPv6 adresses. RaspberryPi isn't IPv6 compatible.
So, we have to add this line in /etc/dovecot/dovecot.conf to disable IPv6 support :
listen = *- Same problem with Postfix. In /etc/postfix/main.cf :
inet_protocols = ipv4- Same problem with Apache. In /etc/apache2/ports.conf :
Listen 0.0.0.0:80
Listen 0.0.0.0:443
