Mailbox & Quota Management

The Mailbox Management card on the Email page is where you control who can receive mail and how much storage they are allowed to use.

Creating Mailboxes

1. Click Add Mailbox.
2. Address: Enter the desired prefix (e.g., info). The domain is automatically appended.
3. Display Name: The name shown to recipients (e.g., Support Team).
4. Quota: Select the initial storage limit.

Understanding the Quota System

DockFlare uses a tiered quota system to ensure your server doesn't run out of disk space while providing a graceful experience for users.

Soft Limit (Quota)

When a mailbox exceeds its configured quota:

• The system inserts a Warning Email from a system address into the user's Inbox.
• The user can still receive mail until they hit the Hard Limit.
• The quota bar in the Master UI will turn Yellow.

Hard Limit (Rejection)

The Hard Limit is automatically calculated as Soft Limit + 15% (minimum 10MB grace buffer).

• Edge Rejection: Rejection happens at the Cloudflare Edge. The sender's mail server receives an SMTP error 5.2.2 Mailbox full.
• The email never enters your R2 transit bucket or your local server, saving bandwidth.
• The quota bar in the Master UI will turn Red.

Catch-all Mailboxes

A Catch-all mailbox receives all emails sent to your domain that do not match an existing, specific mailbox.

1. Click Configure Catch-all.
2. Select a destination mailbox.
3. Click Enable.

Auto-Responders (Vacation Mode)

You can set up automated replies for any mailbox:

1. Click the Auto-Responder icon (robot) next to a mailbox.
2. Enter your message and subject.
3. Set a Date Range for when the responder should be active.
4. Reply Interval: Set how often the responder should reply to the same sender (e.g., once every 24 hours) to prevent "email loops."
