📌 Purpose & Quick Summary

Use the Spam Filter tab to control the server-wide sensitivity score of Apache SpamAssassin. SpamAssassin automatically analyzes every incoming email using Bayesian pattern recognition, DNS blocklists, and header inspection before mail reaches user inboxes.

🖥️ Interface Tour & Elements

  1. Sensitivity Score Slider: An interactive slider ranging from 1.0 (Strict) to 10.0 (Relaxed), with a live numeric badge showing the current threshold (default: 5.0 Standard).
  2. Save Filter Settings Button: Writes the updated score to /etc/spamassassin/local.cf and reloads the spam daemon.
  3. Architecture Information Cards: Four detailed cards explaining why SpamAssassin is enforced at the server level rather than per-user to save VPS CPU and RAM.

🛠️ Step-by-Step Instructions: Adjusting Spam Sensitivity

  1. Open the Spam Filter tab (mail-spam).
  2. Review your current Threshold Score (default is 5.0).
  3. Drag the slider to your desired sensitivity:
    • Strict (1.0 - 3.5): Catches aggressive spam, but may occasionally flag legitimate commercial newsletters. Best for servers receiving heavy spam attacks.
    • Standard (4.0 - 6.0 - Recommended): The ideal balance. Flags over 98% of spam with practically zero false positives.
    • Relaxed (7.0 - 10.0): Only flags obvious, egregious spam.
  4. Click Save Filter Settings.
