Managing SPAM Filters

Beyond SpamAssassin scoring, DirectAdmin lets you define custom spam filter rules for finer control over incoming mail.

Create a filter rule

1. Go to Email Manager → SPAM Filters (or Spam Filters under Advanced Features).
2. Select the domain or mailbox.
3. Click Add Filter.
4. Define conditions — match sender, subject, body text, or headers.
5. Choose an action: discard, move to folder, or mark as spam.
6. Save the rule.

Example rules

• Block mail containing specific keywords in the subject.
• Allow all mail from your company domain.
• Reject messages from known bad senders.

Test new rules carefully. Overly aggressive filters may block legitimate mail.
