This document presents a project proposal for an email server system. It includes an introduction to email servers and how they work. The project aims to set up an email server to allow communication within an organization. It describes the objectives to set up basic email functionality like reading, composing, replying to and forwarding emails. It also covers configuring the email server, including setting up the network topology and IP addresses. The document concludes that email servers provide a simple way to deliver messages between users despite increasing complexity from security standards.

3. INTRODUCTION
AN EMAIL SERVER, ALSO CALLED A MAIL SERVER, IS
ESSENTIALLY A COMPUTER SYSTEM THAT SENDS
AND RECEIVES EMAILS.
WHEN YOU SEND AN EMAIL, IT GOES THROUGH A
SERIES OF SERVERS TO REACH ITS FINAL
DESTINATION.
WHILE THIS PROCESS IS LIGHTNING FAST AND
EFFICIENT , THERE IS A SIGNIFICANT AMOUNT OF
COMPLEXITY BEHIND SENDING AND RECEIVING
EMAILS.

4. AN OVERVIEW
To receive emails, you will need an email
account and an email address. Also, if
you want to send emails to other
people, you will need to obtain their
email addresses.
It's important to learn how to write email
addresses correctly because if you do
not enter them exactly right, your emails
will not be delivered or might be
delivered to the wrong person.

5. PROJECT DESCRIPTION
At its simplest, a mail server collects and distributes emails to their intended
destination.
You can think of it as a computer that acts as an electronic post office for email,
which allows you to control the transfer of emails within a network through
different protocols.

7. SCOPE
Sending and receiving emails is a complicated process that
increases in complexity with every new regulation and
security requirement.
And yet, even with all the evolving security standards,
your messages can still be falsified or forged, putting
you at risk for cyber-attacks.
Since email is the main target for these attacks, you need
to provide extra email protection, especially as a
business.

CONCLUSION
10/25/2022 9:30:44 PM
Email servers, though at first glance might seem
daunting, are actually very simple systems
designed to deliver text messages (and now
attachments) from point A to point B.
The system’s core principles remain unchanged,
but new technologies and solutions are being
developed every day to allow greater reliability,
security, and convenience.
