How to Set Up Email Hosting with Your Own Domain on DirectAdmin

Why Use Email with Your Own Domain?

Using a custom domain email like [email protected] instead of a free Gmail or Hotmail account offers significant advantages for businesses of all sizes — from professionalism and brand credibility to full control over your data.

Free Email (Gmail)	Email Hosting with Own Domain
[email protected]	[email protected]
Less professional	High brand credibility
Limited account control	Unlimited accounts
15 GB shared with Drive	Storage per Hosting plan
Dependent on Google	Full control via DirectAdmin

Prerequisites

Before setting up Email Hosting, make sure you have these ready:

• A registered domain — e.g., yourbusiness.com, yourbusiness.co.th
• A Web Hosting plan that supports Email Hosting (all AsiaGB Hosting plans include it)
• DNS Management access to your domain for setting MX Records
• DirectAdmin login credentials — Username, Password, and Control Panel URL

Configure MX Records

MX Records (Mail Exchanger Records) are DNS settings that tell email systems which mail server handles incoming emails for your domain. If your domain and hosting are with different providers, you need to update MX Records manually.

Create Email Account in DirectAdmin

Once DNS is ready, create your Email Account in DirectAdmin:

Access Webmail

After creating an Email Account, you can access Webmail immediately — no software installation needed.

• Open your browser and go to https://yourdomain.com/webmail
• Or https://mail.yourdomain.com
• Log in with your full Email Address, e.g., [email protected], and password
• DirectAdmin includes Roundcube Webmail — clean, modern interface that works on any device

Configure Mail Client (Outlook / Gmail / iOS)

For convenience, you can configure your Email Hosting on any Mail Client using IMAP (recommended) or POP3.

Setting	IMAP (Recommended)	POP3
Incoming Server	mail.yourdomain.com	mail.yourdomain.com
Incoming Port	993 (SSL)	995 (SSL)
Outgoing (SMTP)	mail.yourdomain.com	mail.yourdomain.com
SMTP Port	465 (SSL) or 587 (STARTTLS)	465 (SSL) or 587 (STARTTLS)
Username	Full Email Address	Full Email Address
Password	Email password	Email password

Set Up on Microsoft Outlook

1. Open Outlook, go to File → Add Account
2. Enter your Email Address, click Advanced options → Let me set up my account manually
3. Select IMAP and enter the server settings from the table above
4. Test the connection, then click Done

Add to Gmail (Send mail as)

3. Select IMAP and enter Incoming/Outgoing Mail Server details
4. Save — iOS will verify the settings automatically

Set Up SPF, DKIM and DMARC

Configuring SPF, DKIM, and DMARC prevents your emails from being filtered as spam and improves email deliverability.

SPF Record (Sender Policy Framework)

SPF specifies which IP addresses or servers are authorized to send email from your domain. Add a TXT Record in DNS:

DKIM (DomainKeys Identified Mail)

DKIM adds a digital signature to every email to verify it came from your domain. DirectAdmin has a built-in DKIM generator:

1. In DirectAdmin, go to Email Management → DKIM Keys
2. Click "Generate DKIM Key"
3. Copy the TXT Record and add it to your domain's DNS Zone

DMARC Record

DMARC sets a policy for emails that fail SPF/DKIM checks. Add a TXT Record:

Email Forwarder and Catch-All

DirectAdmin includes Email Forwarder functionality that automatically redirects emails from one address to another.

Create an Email Forwarder

1. Go to Email Management → Forwarders
2. Click "Add Forwarder"
3. Specify the Source Email and Destination Email (can be an external address like Gmail)
4. Save — emails to the Source will be forwarded to the Destination immediately

Catch-All Email

Catch-All receives every email sent to any address at your domain, regardless of what comes before the @. Useful for ensuring no emails are missed.

1. Go to Email Management → Catch-All
2. Enable it and specify the receiving email address

Set Up Autoresponder

Autoresponder sends automatic replies when emails are received — ideal for out-of-office notifications or acknowledgment messages.

1. Go to Email Management → Autoresponders
2. Click "Add Autoresponder"
3. Select the Email Account
4. Set the Subject and message body
5. Optionally set Start/End Dates for temporary use
6. Save
