1) Use fetchmail (as root) to get the messages from your IPS. look for headers like "Envelop-To" or "Delivered-to" and make fetchmail use those to distinguish the real addressee and have fetchmail deliver them locally (via exim or procmail) into the mailbox of that addressee. 2) Set up a localnet only POP/IMAP server on your firewall and set up each family member's machine to get mail from the POP/IMAP server on that firewall. Make sure that POP/IMAP server isn't listening to pop/imap requests coming from the internet, or better have a firewall rule prevent such connections from being setup in the first place. 3) Set up a MTU (e.g. exim) on your firewall using its "smarthost" ability to deliver all localnet mail to your IPS, and set up each family member's machine to use the smtp port of your firewall. Make sure that exim doesn't listen on the 'external' ethernet, or better use a firewall rule to prevent incomming smtp connections to succeed. 4) consider moving all the above from the firewall as this will increase security! -- groetjes, carel
