Hi all,
I am planning to configure sendmail as a mail router. I have subscribed to a mail server which I can access through POP and SMTP. I have a group of users on a LAN who have email accounts on that mail server and I have a 24x7 leased line connection. My question is, is there any way to configure sendmail to act as a mail router, thereby relaying all the mails from my lan to the mail server and vice-versa?
As I have mentioned that I'm planning to implement this,the hardware config is:
Intel Original 945 MBD, with SATA HDD, 1 GB RAM. Could you please reccomend me a distribution that I can use?. I have used Redhat 8,9,EL-4 before and am using Mandriva2006 now.
Thank a lot guys, awaiting your response.

First hit from a google.com/linux search looks like a good starting point:
