On the machine you want to be the mail hub, configure it to accept mail for your (local) domain. On the other machines, tell them to send all local mail to the mail hub for delivery and to use it as a smart host also.
A quick example is in order, me thinks. I have three Linux machines here along with various flavors of Windows. "hurricane" is the (internal) mail server (i.e. no direct Internet connection). The two other Linux machines, "kerberos" and "earthquake" are set to send all local mail to "hurricane", e.g.: [EMAIL PROTECTED]:pts/0:~]$ grep ^DH /etc/mail/sendmail.cf DHhurricane.home.lan The three Linux machines pass off any mail to "hurricane", where it is stored. "hurricane" uses "kerberos" as a smart host, since it's the only machine directly connected to the Internet, e.g.: [EMAIL PROTECTED]:pts/0:~]$ grep ^DS /etc/mail/sendmail.cf DSkerberos.home.lan "kerberos" then uses my ISP's mail server as it's smart host, and lets it deal with the task of getting the mail to its final destination, e.g.: [EMAIL PROTECTED]:pts/0:~]$ grep ^DS /etc/mail/sendmail.cf DSmoseisley.blueriver.net To illustrate this a bit, all my e-mail is stored on my ISP's mail server. When I dialup (on "kerberos", the machine with the modem), fetchmail is started and grabs my mail roughly every 300 seconds. fetchmail hands it off to sendmail on "kerberos" which has been told to send all local e-mail to "hurricane" for delivery. "kerberos" then contacts "hurricane" and gives it the message, which is then passed to procmail which filters it and puts it into its appropriate place under /home/jeremy/Mail/. When I'm done typing this message and hit "Send", the machine I'm sitting at "tremor" will send it to "hurricane" (my internal mail server, remember?) which will see that it's a "non-local" email and pass it off to "kerberos", who in turn, will give it to my ISP. (Take a look at the mail headers.) See, easy? :) This keeps all the e-mail centralized in one place. As far as reading e-mail goes, I use a variety of clients depending on where I'm at. If I'm here at home, it's usually Outlook. If I'm logged into the mail server itself, I'll use mutt. If I'm on one of the other Linux machines, I'll use Pine (configured for IMAP). If I'm somewhere else, I can use one of the webmail systems I have set up. To summarize, keep all your e-mail situated on one server and use mail clients that support IMAP. Store your e-mail on the server instead of the client, and your life will be lots easier. This ended up longer than I expected, but hopefully it'll help you out. It's not hard to set up, but when it is, it makes your life alot easier. :) j. -- Jeremy L.

I use one as a router to masq the other two to the internet. I would also like to use this one as the mail hub. There is only one user for the three boxes. What I would like to do is to be able to read my mail from any box but still save it on the hub. So that if I want to refer to a saved msg from a different box I can get to it. The router is running debian 2.2r3 using fetchmail-sendmail-procmail-mutt to deal with mail. The way it is currently set up I have to read and send all mail from this box. The other 2 boxes are using progeny-debian. I went this route primarily because of the ease of X configuration with progeny. They also have the same mail pkgs installed. So, my question is, how can I set the network up to be able to send/read mail from any box but store all mail on the hub? Thanks, Jay Latham Beer is proof God loves us and wants us to be happy!
