How to send and receive emails through mail clients without internet connection in computer

In some case we need to access Emails in different system. Normally the system admin provides internet connections to all those system to get mail or use some software's like Mdaemon or Exchange server to share emails. But it's costly method, small offices can't afford it. so we can use this simple method to share mails.

Check List
1, In all case you need to configure a mail client to access emails.
2, Mail client configuration, you had provided POP and SMTP server address.  
3, Identify your Internet Gateway
4, Get these POP and SMTP server IP address by pinging.
5, If both POP and SMTP servers are using same IP, then create a Route add
6, If different IP's then create separate Route add for POP and SMTP.

See the Example:
My Email Server is Gmail and mail client is Outlook Express.
Gmail POP Server : pop.gmail.com
Gmail SMTP Server: smtp.gmail.com
To get POP server IP, use command prompt and type the following command

ping pop.gmail.com
I get, POP server IP is 74.125.53.109
ping smtp.gmail.com
I get, SMTP Server IP is 74.125.95.109

now I create 2 route add for sending and receiving mails because of SMTP and POP server address are different. First I create route add for POP  Server

In Command prompt using this command route add "target ip" mask  "subnet mask"  "internet gateway" -p
-p : Makes a route persistent across boots of the system.


route add 74.125.53.109 mask 255.255.255.255 10.116.84.161 -p


create 2nd route add for SMTP by changing Target IP.

This method useful for  those system which are now connected to internet only for email usage and also reduce the internet usage.

Note : Please remove Gateway and DNS from TCP/IP Network protocol.
