This document is a tutorial on configuring a mail server using Cisco Packet Tracer, detailing the setup of PCs and servers including a mail server and a DNS server. It explains the assignment of IP addresses, setting up SMTP and POP3 services on the mail server, and configuring the DNS service. Finally, it illustrates how to use the mail application on PCs to send and receive emails.

1. Configuration of mail server on cisco packet tracer
1. In this tutorial we will learn how to set mail server on cisco packet tracer.
2. As you can see on below picture we have taken 4 PCs and 2 Servers (1 mail server and 1 DNS server)
3. DNS stands for Domain Name System which will convert IPs to Email address.
4. We assign IPs to each PC and Server. It is required to keep IP in same network because here is connected
network by single switch. There is no layer 3 device and VLAN.
5. We assign IP to mail server 192.168.1.1 255.255.255.0 and 192.168.1.2 255.255.255.0 to DNS server. Rest next
IPs to each connected PC(192.168.1.10 192.168.1.11 192.168.1.12 192.168.1.13 with same subnet mask
255.255.255.0)
6. Let’s go ahead in mail server, set a domain name like gmail.com, yahoo.com, redifimail.com or it can be as per
your choice. Tick SMTP Service on and POP3 Service on. Create usernames and passwords.

2. 7. Then we move to DNS server and select DNS service, tick the DNS service on. We provide same domain name
and IP which we put on mail server. After that click on add.
8. Now we can login on PC Mail application with usernames and passwords which have been created on mail
server.

3. 9. Your mail account is ready to send and receive mails, like I type from Wouter mail account Hi to Lucky. Let’s see
Lucky received mail or not.
