Understanding Mail Server Host Name: A Complete Guide for Dev

Greetings Dev! In this article, we’ll be discussing the basics of mail server host name. If you’re new to email hosting or are looking to improve your knowledge in this area, then you’ve come to the right place!

What is Mail Server Host Name?

Before we dive into the details, let’s first define what we mean by “mail server host name.” Simply put, it is a unique identifier that is used to distinguish one mail server from another. Every mail server has a unique host name that is used to route emails to the correct server.

For example, if you have a domain name like mydomain.com and you want to set up email hosting for it, you will need to have a mail server host name. This host name will be used by your domain registrar to point your domain to the correct mail server.

Parts of a Mail Server Host Name

A mail server host name is made up of two main parts: the domain name and the host name.

Let’s take a closer look at each of these parts.

Domain Name

The domain name is the most important part of a mail server host name. This is because it identifies the email domain that is being hosted. The domain name will be the same for all email addresses hosted on that server.

For example, if you have the email address john@mydomain.com, the domain name in this case would be “mydomain.com.” This is the domain that is associated with all email addresses hosted on that server.

Host Name

The host name is the part of the mail server host name that identifies the specific mail server that is being used. This is an important distinction, as there may be multiple mail servers associated with a single domain.

For example, if your domain registrar is pointing your domain to a mail hosting provider, that provider may have multiple mail servers that are used to handle incoming and outgoing emails. Each of these servers will have a unique host name that is used to identify it.

How Mail Server Host Names Work

When you set up email hosting for your domain, you will need to provide your domain registrar with your mail server host name. This host name will then be used by your registrar to point your domain to the correct mail server.

When someone sends an email to your domain, their email client will look up the MX record (mail exchange record) for your domain. This record will contain the mail server host name that is associated with your domain.

The email client will then use this host name to connect to the correct mail server and deliver the email.

MX Records

MX records are a type of DNS (domain name system) record that is used to specify the mail server(s) that are responsible for handling incoming emails for a domain. When you set up email hosting for your domain, you will typically be provided with a set of MX records that you can use to configure your domain’s DNS settings.

It’s important to note that MX records are not used to handle outgoing emails. Outgoing emails are typically sent directly from the email client to the recipient’s mail server.

Choosing a Mail Server Host Name

Choosing a mail server host name can be a bit tricky, as there are several factors that you will need to take into consideration.

Availability

The first thing you will need to consider is the availability of the host name. You will want to choose a host name that is not already in use by another mail server. This can be a bit challenging, as many common host names may already be taken.

If you’re having trouble finding an available host name, you may want to consider using a more unique name that is less likely to be taken.

Relevance

Another factor to consider is the relevance of the host name to your domain. You will want to choose a host name that reflects the name of your domain or the name of your organization.

For example, if your domain is mycompany.com, you may want to choose a host name like “mail.mycompany.com” or “mycompany.mailserver.com.”

Security

Finally, you will want to consider the security implications of your host name. Certain host names may be more susceptible to phishing attacks or other types of email scams.

For example, if you choose a host name like “webmail.mycompany.com,” attackers may be more likely to target this host name in their scams.
