Creating an email account

  1. Log into the user’s DirectAdmin panel.
  2. Go to Email Manager → Create Email Account.
  3. Enter the username (part before @), select the domain.
  4. Set a password and storage quota in MB.
  5. Click Create Account.

Webmail access

DirectAdmin typically ships with Roundcube:

https://yourdomain.com/roundcube

Or access it from the DirectAdmin panel: Email Manager → Webmail.

Managing quotas

To change a mailbox quota:

  1. Email Manager → Email Accounts
  2. Click the email address
  3. Update Quota (MB): enter 0 for unlimited
  4. Click Modify

Monitor overall disk usage to ensure users don’t fill the server. Each account has a total disk quota set by its hosting package.

Email forwarders

To forward email from one address to another:

  1. Email Manager → Forwarders → Add Forwarder
  2. Enter the source address and destination
  3. Click Create

Catch-all address

  1. Email Manager → Catch-All Email
  2. Select the domain
  3. Set the destination (forward to an address, or discard)
  4. Save

Catch-all attracts spam: Setting a catch-all that forwards to a real mailbox floods it with spam from dictionary attacks. Use Discard unless you have a specific need for catching misspelled addresses.

Spam filtering

DirectAdmin uses SpamAssassin. Configure it per user:

  1. Email Manager → Spam Filters
  2. Enable spam filtering, set the score threshold
  3. Choose action: tag subject, move to folder, or delete

Emails scoring above the threshold are flagged or moved automatically.
