Email Setup & Quota in DirectAdmin

Creating an email account

Log into the user's DirectAdmin panel.

Go to Email Manager → Create Email Account.

Enter the username (part before @), select the domain.

Set a password and storage quota in MB.

Click Create Account.

Mail client settings

Setting	Value
IMAP server	Your server hostname
IMAP port	993 (SSL/TLS)
SMTP server	Your server hostname
SMTP port	587 (STARTTLS) or 465 (SSL)
Username	Full email address
Password	Account password

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

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.
