The document provides instructions for setting up a mail server on Cisco Packet Tracer, including assigning IP addresses to 4 PCs and 2 servers (a mail server and DNS server), configuring the mail server domain name and user accounts, setting up the DNS server to direct to the mail server IP, and testing email send and receive between the PCs.

1. 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.

2. Build the network topology
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 192.168.1.2 Subnet mask 255.255.255.0
and DNS Server 192.168.1.3 Subnet mask 255.255.255.0 .
Rest next IPs to each connected PC
PC0 -- 192.168.1.4 PC1 -- 192.168.1.5
PC2 -- 192.168.1.6 PC3 -- 192.168.1.7
With same subnet mask 255.255.255.0

3. 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.
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.

4. 8. Now we can login on PC Mail application with usernames and passwords which
have been created on mail server.

5. 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.

6. 10. Now Check the message.
