Creating professional, custom email addresses using your own domain name (such as [email protected], [email protected], or [email protected]) is essential for establishing brand credibility, enhancing security, and managing customer communications effectively.

DirectAdmin provides a powerful, built-in E-mail Manager that makes creating, organizing, and securing custom mailboxes straightforward. You can easily allocate custom storage quotas, set daily sending limits, access your inbox via Roundcube Webmail, and connect to third-party mail clients such as Microsoft Outlook, Apple Mail, Mozilla Thunderbird, Gmail, and smartphone mail applications.

In this step-by-step tutorial, we will guide you through creating an email account in DirectAdmin, accessing Webmail, configuring email client settings (IMAP / POP3 / SMTP), and managing mailbox storage.

  2. Via DirectAdmin: In the left navigation menu under Extra Features (or System Info & Files), click Webmail: Roundcube.
  3. Enter your full email address (e.g. [email protected]) and your password to sign in.

Configuring Email Clients (Outlook, Apple Mail, Thunderbird, Gmail, Mobile)

Managing Your Email Accounts in DirectAdmin

  • Change Password: Click the three dots () next to an account > select Change Password > enter a new password > Save.
  • Modify Quota: Click the three dots () > select Change Limits to adjust storage allocation or send limits.
  • Suspend / Unsuspend: Select an account and click Suspend to temporarily halt sending/receiving without deleting stored mail.
  • Delete Account: Select the checkbox next to an account and click Delete to permanently remove the mailbox and all its messages.
  • Email Forwarders: Navigate to E-mail Manager > Forwarders to forward incoming copies automatically to external addresses (e.g. Gmail or Yahoo).
  • Autoresponders: Navigate to E-mail Manager > Autoresponders to set up automatic "Out of Office" holiday replies.

Frequently Asked Questions & Troubleshooting

Q: Why can't I send or receive emails on my new domain?
A: Ensure that your domain's DNS records include an active MX record pointing to mail.domain.com and that your nameserver DNS propagation is complete (typically 1 to 24 hours).

Q: Should I choose IMAP or POP3 when setting up my email app?
A: We strongly recommend IMAP. IMAP keeps all your emails, sent items, and folders synchronized across your computer, phone, tablet, and Webmail. POP3 downloads messages locally to one device and deletes them from the server.

Q: Why does my email client show an "Untrusted Certificate" warning?
A: Make sure your free Let's Encrypt SSL certificate covers the mail.domain.com host. In DirectAdmin, go to Account Manager > SSL Certificates > select Free & automatic certificate from Let's Encrypt, check both domain.com and mail.domain.com, and click Save.

Q: What should I do if my mailbox is full?
A: When a mailbox exceeds its quota, incoming emails will bounce back to senders. To resolve this, log in to DirectAdmin, go to E-mail Accounts, click Change Limits on the account, and increase the E-mail Quota (MB) or check Max.
