How to Use DirectAdmin Webmail on Mobile: iPhone & Android Step-by-Step Guide

DirectAdmin Webmail lets you read and send emails from anywhere using just a mobile browser — no extra apps required. This guide covers how to use RoundCube Webmail on iPhone and Android, plus how to set up IMAP/SMTP so your native mail app can sync with your DirectAdmin email account.

What Is DirectAdmin Webmail?

DirectAdmin ships with RoundCube Webmail, a widely-used, mobile-responsive webmail client. RoundCube offers full email management including folder organisation, search, contacts, and attachments — all accessible from any mobile browser.

• No installation needed — open in any mobile browser and log in
• Responsive design — RoundCube adapts its layout for small screens
• Secure HTTPS access — all data encrypted in transit
• Real-time IMAP sync — emails stay on the server, always up to date

Webmail URL for Mobile Access

Open any mobile browser and navigate to one of these URLs:

• https://yourdomain.com:2096 — standard DirectAdmin Webmail port (recommended)
• https://mail.yourdomain.com — if your hosting provider has configured the mail subdomain
• https://yourdomain.com/webmail — available on some hosting setups with redirect configured

Replace yourdomain.com with your actual domain name. All AsiaGB Hosting plans support all three access methods.

How to Log In to Webmail on Mobile

Once you open the Webmail URL, RoundCube presents a login screen. Enter:

1. Username — must be your full email address, e.g. [email protected] (not just info)
2. Password — the email account password set in DirectAdmin (not the control panel login)
3. Tap Login

If login fails, verify that you are using the full email address and the correct email password from DirectAdmin Email Accounts, not your hosting control panel password.

Using RoundCube Webmail on iPhone (iOS)

iPhone users can access RoundCube Webmail through Safari or Chrome. For the best experience:

1. Open Safari or Chrome on your iPhone
2. Navigate to your Webmail URL, e.g. https://mail.yourdomain.com
3. Log in with your full email address and password
4. Tap the Share button (box with arrow) → "Add to Home Screen"
5. RoundCube will open in a fullscreen view just like a native app

Push Notifications on iPhone

iOS Safari has limited Web Push Notification support for background updates. For reliable push notifications when new mail arrives, configure IMAP in the Apple Mail app as described below.

Using RoundCube Webmail on Android

Android supports Webmail through Chrome, Firefox, or any modern browser, with optional PWA-style installation:

1. Open Chrome on your Android device and visit the Webmail URL
2. Log in to your email account
3. Tap the three-dot menu → "Add to Home screen"
4. Name the shortcut and tap Add
5. The icon appears on your Home Screen like a native app

Android Chrome fully supports Web Push Notifications for RoundCube when the hosting server has the necessary plugin installed.

Setting Up IMAP/SMTP on Apple Mail (iPhone/iPad)

Configuring IMAP in Apple Mail gives you push notifications and offline access to recent emails.

1. Go to Settings → Mail → Accounts → Add Account
2. Choose Other → Add Mail Account
3. Enter your name, email address, password, and a description, then tap Next
4. Select IMAP and fill in the server settings below

Setting	Value
Incoming Mail Server (IMAP)	mail.yourdomain.com
IMAP Port	993 (SSL/TLS)
Username (IMAP)	[email protected]
Outgoing Mail Server (SMTP)	mail.yourdomain.com
SMTP Port	587 (STARTTLS) or 465 (SSL)
Username (SMTP)	[email protected]

Replace yourdomain.com with your actual domain and user with your mailbox username. iOS will verify the connection automatically after you tap Save.

Setting Up Email on Android (Gmail App / Samsung Mail)

Both the Gmail App and Samsung Email support DirectAdmin IMAP accounts.

Gmail App Setup

1. Open Gmail → tap your profile picture → Add another account
2. Select Other
3. Enter your full email address and tap Next
4. Choose Personal (IMAP)
5. Enter your password and tap Next
6. Incoming Server: mail.yourdomain.com, Port: 993, Security: SSL/TLS
7. Outgoing Server: mail.yourdomain.com, Port: 587, Security: STARTTLS
8. Tap Next to verify and save

Troubleshooting Common Issues on Mobile

Cannot Log In

• Ensure you use the full email address (e.g. [email protected]), not just the username
• Use the email account password, not the DirectAdmin control panel password
• Reset the email password in DirectAdmin → Email Accounts if needed

SSL Certificate Warning

• Install a valid SSL certificate via DirectAdmin → SSL Certificates (Let's Encrypt is free)
• Temporarily use port 2095 (HTTP) if no SSL is set up — but avoid this for production use

IMAP Connection Fails

• Confirm your hosting plan supports IMAP (all AsiaGB Hosting plans do)
• Check whether a VPN or mobile firewall is blocking port 993
• Try port 143 with STARTTLS as an alternative to 993

Mobile Email Security Best Practices

• Always use HTTPS — never access Webmail over HTTP, especially on public Wi-Fi
• Use a strong password — at least 12 characters mixing letters, numbers, and symbols
• Log out after each session — especially on shared or public devices
• Enable DirectAdmin 2FA — prevents unauthorised changes to your email passwords
• Keep iOS/Android updated — to receive the latest security patches

Summary: DirectAdmin Webmail on Mobile

RoundCube Webmail works in any mobile browser with no setup required. For push notifications and offline access, configure IMAP in Apple Mail or Gmail App using your DirectAdmin server settings. Both approaches use the same secure SSL/TLS encryption, keeping your emails protected on mobile.
