Processing rules
Flexible, condition-based mail routing and processing.
What rules are
Processing rules are sets of conditions and actions applied to every inbound message after the anti-spam analysis. Use them to automatically sort, forward, and tag messages.
Conditions (If)
Each rule checks one or more conditions. Conditions can be combined with AND (all must match) or OR (at least one must match).
| Condition type | Description | Example |
|---|---|---|
| From | Sender address or domain | @newsletter.com |
| To | Recipient address or domain | ceo@company.com |
| Subject | Match in the subject line | INVOICE |
| IP address | Sending server's IP or subnet | 10.0.0.0/8 |
| Header | Any message header | X-Mailer: MailChimp |
| Body keyword | Keyword in the message body | unsubscribe |
Actions (Then)
- Mark as spam — raise the message's score above the threshold
- Deliver — force delivery, bypassing quarantine
- Reject — bounce to the sender with a 550 code and a custom message
- Forward to email — send a copy to another address
- Forward to server — deliver to an alternate SMTP server
- Add to subject — prepend a prefix to the subject line
- Add header — insert a custom header into the message
Order of evaluation
Rules are evaluated in the order they appear in the list. You can drag rules to change their priority. The "Stop processing other rules" flag halts further processing once a rule matches.
