I am using Redhat Linux 7.2 for my organisations Intranet & have moderate knowledge on Linux. Let me give the Configuration. I have setup one Linux Box(xyz.co.in) as the Gateway for internet Connection. This box has two ethernet cards. one is connected to my LAN network other to the VSAT router of my VSAT Provider for Internet. I have registered Domain name xyz.co.in. This domain name is now used for mails only. The named service & IPChain are running in this linux box. I have setup another Linux Box(imap.xyz.co.in) as Mail server in which I set up the Sendmail service and configured the user mailboxes. Also the squid Proxy server is running in this Linux box. All the users can send mail internally as well as to external world. Also they can receive mails from outer world. for this I have configured the Genericstable & Virtusertable in the first linux box. e.g. if a user name is 'bob' then the entry in genercstable is
and in Virtusertable th entry is
Now my Problem is to provide the Mail facility to the users of other office of my organisations which is located farway. My management wants that all the people in that office should have mailboxes in the above mailserver and they can access(send & receive) their mails with the same domain name.
How can I configure for acheiving this result.
Any solutions for this?
Thankx & regards
