Is this a homework question?

There are a number of incongruencies

LAN-A is 172.16.124.54, Subnet-255.255.255.0, g/w-172.16.123.1.
Gateway is in a different subnet than lanA

for the smtp/pop services
What do you mean? Actual services or do you mean like Outlook?

Do you understand you can accomplish what it appears you desire with far less complication? Vlans

brother i have given the ip & g/w of LAN-B which are correct and working. this lan is not under my administration. However, LAN-A is under my control. My requirements are:
1) use a windows server 2003 in LAN-A as smtp/pop server.
2) connect lan-a to this server and send/receive messages through outlook.
3) connect one pc (win xp) in lan-b to this server (on 2nd NIC) and send/receive messages through outlook.
4) most important no pc on LAN-B should be able to access my files in LAN-A. If possible no LAN-A pcs should be visible on LAN-B PCs.
5) Ip of LAN-B (srry not lan-a) is 172.16.124.54, Subnet-255.255.255.0, g/w-172.16.123.1. the IP of LAN-A is 192.168.30.xx

"Ip of LAN-B (srry not lan-a) is 172.16.124.54, Subnet-255.255.255.0, g/w-172.16.123.1."

172.16.124.54
172.16.123.1
x.x.124.x
x.x.123.x
you can not have a gateway for
172.16.124.x with
172.16.123.y

These are different subnets. Your gateway resides in the same subnet. You need a x.x.124.x gateway.
Make sense?

"use a windows server 2003 in LAN-A as smtp/pop server."

Do you understand that you need a public domain name to do this? That domain name has to have a public MX record that points to your server.

You would put in a gateway router between lanB and lanA. This way no one can access lanA from B unless you provide a route. You would open up the pop/smtp ports in the router to let that pass through.

Why do you think you need a mail server?
