What Is a Host Name for Email?

An email host name is the server responsible for sending and receiving your emails. It functions like a digital post office, operating continuously to ensure your emails are delivered and received. Examples of email hosts include Gmail, Microsoft Outlook, and Yahoo.

Knowing your host name is crucial when configuring your email on devices or apps like Apple Mail. Inputting the host name details correctly means you can send and recivie emails.

What Is an Example Email Host Name?

Email host names typically include two main components:

1. SMTP (Simple Mail Transfer Protocol): This is your outgoing mail server host name, which handles sending emails.
2. IMAP (Internet Message Access Protocol): This is your incoming mail server host name, which retrieves emails and synchronizes them across devices.

You may also encounter POP3 (Post Office Protocol), another method for receiving emails. Unlike IMAP, which syncs emails across devices, POP3 downloads and removes emails from the server, making it less commonly used today.

Example Host Name Settings:

• Incoming Mail (IMAP) Server:
  imap.mail.yahoo.com (Port: 993)
• Outgoing Mail (SMTP) Server:
  smtp.mail.yahoo.com (Port: 465 or 587)

How to Find Your Email Host Name

1. Identify Your Email Provider

The domain following your email address (e.g., @gmail.com) usually indicates your provider. For example, an email ending in @outlook.com suggests Microsoft Outlook is your host.

For custom email domains (e.g., @yourdomain.com), follow the section below for specific guidance.

2. Refer to Provider-Specific Guides

Most popular email providers publish their host name settings on support pages.

Below are some useful links:

• Gmail Host Name Settings
• Outlook and Hotmail Host Name Settings
• Yahoo Host Name Details
• Apple Mail Host Name Information

If you cannot locate your provider’s host name, searching online for “{Your email provider} host name settings” can help.

Finding the Host Name for a Custom Business Email?

If you have a custom email domain (e.g., @yourdomain.com) and are unsure of the host name, try these approaches:

1. Contact Your Email Hosting Provider
   Good hosting providers should offer clear support for email configuration. Log into their platform or reach out to their customer service team. They can provide the IMAP/SMTP host name and guide you through the setup process.

2. Check Your Domain’s DNS MX Records
   Your domain’s DNS records often contain the required information. To locate your host name:

   • Log in to your domain registrar or hosting control panel.
   • Access the DNS settings and look for the MX record.
   • The domain listed in the MX record is usually your email host.
     Example:
     • MX Record: mail.customhost.com
       Host Name: customhost.com

Connecting Your Email to Other Email Apps

When configuring your email in a client like Apple Mail or Outlook, you’ll typically need these details:

• Username and Password
• Outgoing Mail Server Host Name (e.g., smtp.provider.com)
• Outgoing Mail Server Port (e.g., 465 or 587)
• Incoming Mail Server Host Name (e.g., imap.provider.com)
• Incoming Mail Server Port (e.g., 993 or 143)

Most email providers list these details on their websites in the links above. If issues persist, contact your hosting provider or search for specific setup instructions.

Important Update for Gmail Users (2025 Onward)

Starting January 2025, Gmail requires OAuth2 authentication for third-party email clients, eliminating traditional password logins.

To use Gmail in other email apps….

1. Enable IMAP in Gmail
   • Go to Settings > See all settings > Forwarding and POP/IMAP.
   • Enable IMAP and save changes.
2. Use OAuth2 Authentication
   • Look for the “Sign in with Google” option in your email app.
3. Generate App-Specific Passwords
   • For apps that don’t support OAuth2, create an app-specific password via your Google account settings.
