What Is an Email Server?
Emails are the backbone of today’s business world. No matter the size or the industry of the business, the bulk of corporate communication is done via mail, both inside the company and with outside partners and institutions.
And as a lot of sensitive personal and professional information is shared, individuals and firms seek safer and more efficient solutions regarding sending, receiving, and storing e-messages.This is where email servers come into play. In this article, we will cover everything you need to know about them, from what they are and how they work to choosing the right electronic mail host for you and your business.
The Basics of Email Servers
An email server is a computer system that is dedicated to receiving and sending mail. It works with other related programs and applications to create a comprehensive messaging environment that works without any interruptions.
For example, when you send an online message via a program like Microsoft Outlook or Gmail, it forwards the message to an email server. Then, the host scans the transmission and sends it to another location or to a holding space on the same one, depending if the recipient uses the same program as you or a different one.
Benefits of Email Servers
Email hosts offer you quite a few benefits.
First, they allow you to have inboxes with your own domain name, which gives you better credibility and improves brand reputation. If you go for a VPS solution, you can also enjoy enhanced security, thanks to great extras like a dedicated IP or advanced spam procession.
More so, you can easily organize collaborative schedules, as many services offer you shared calendars. Not to mention tailored email functionality like webmail, forwarders, autoresponders, and more. All this enhances your functionality and productivity, making web hosts the perfect choice for your business.
Difference Between Mail Clients and Mail Servers
Mail clients and mail servers are part of the sending and receiving message process. However, they have different roles. A mail client refers to an app that enables you to manage, format, and send online messages.
In comparison, email hosts are software programs that use mail protocols so they can improve the transmission of messages between clients.
More precisely, when you compose a mail and address it to the intended recipient, the host accepts the message, transfers it, and delivers it to the corresponding inbox.
Understanding Email Servers
In order for a computer system to serve as a mail server, it must be equipped with such server software, which allows the administrator to create and manage accounts for the domains.
Additionally, there are two types of e-message servers, including the following:
Incoming Email Servers
Incoming email servers store messages and send them to a user’s inbox. There are two main types, including:
- POP3 or Post Office Protocol 3: They download and store incoming messages on a single device. Then, once the user opens it and downloads the electronic mail, they are automatically deleted from the server. However, you can also keep them. Additionally, most users prefer the POP3 protocol because it is simple, allows you to download and read your mail offline, and is more efficient.
- IMAP or Internet Message Access Protocol: These servers enable you to preview, organize, and delete emails before they transfer them to multiple devices. IMAP hosts also keep copies of them until deleted.
Outgoing Email Servers
Outgoing email servers use the SMTP or Simple Mail Transfer Protocol to manage the delivery process and send e-messages. More specifically, SMTP works with other mail hosts, like POP3 and IMAP, resulting in a seamless delivery and sending process.
How Does an Email Server Work?
To better illustrate the role of email servers, let’s see what the sending process looks like and what they do to make it happen. It goes as follows:
- The user writes a message and uses a third-party email client to send it.
- The client establishes a connection to the SMTP.
- The SMTP processes the composition and attachments of the mail and identifies the recipient’s address.
- If the recipient and sender have the same domain name, the message is directly transmitted via POP3 or IMAP. Otherwise, if they have different domain names, the SMTP uses the domain name system or DNS, which translates the mail domain name into an IP (Internet Protocol) address, to find the recipient’s server.
- The IP address of the recipient connects to the SMTP host, and once it is identified, the intended message travels through unrelated SMTPs until it reaches its final destination.
- The recipient’s SMTP then handles, checks, and directs the online message over to an IMAP or POP3 server so that it ends up in their inbox.

With email server hosting, you rent a server from a hosting provider for a monthly fee. This solution enables you to cut down on your costs because you won’t have to manage and maintain your own servers.
Also, most providers offer business email hosting, where your own domain is included in your electronic mail address. This can make you appear more trustworthy to customers and partners.
Moreover, the provider you pick can either host your mail on the same server as your website or it can provide a separate one. Of course, you can also choose to host them with different providers if you wish.
Compared to email hosting, web hosting involves the server space for website owners to store their files and data. This allows your customers to access your site and view it online.
In a web hosting plan, you get various tools and technologies within the server space. More precisely, there are software and hardware tools. For example, software tools are a content management system, a web server, and a database, while hardware tools include a network and a storage device.
