Kaspersky Warning + Email Error Breakdown

You’re dealing with two connected issues here:

🛑 Kaspersky Warning + Email Error Breakdown

1. Kaspersky: “Protection is disabled”

  • The red X and alert means protection is off, and some features are blocked.
  • This can interfere with email traffic—especially if Kaspersky is scanning encrypted connections (SSL/TLS filtering) or blocking ports.

2. Foxmail Error: “No such host is known”

This means:

  • Your email client can’t resolve the email server hostname (like mail.yourdomain.com) into an IP.
  • Possible causes:
    • DNS resolution issue (wrong hostname or no internet).
    • Firewall or antivirus blocking.
    • The mail server is offline or incorrectly configured.

âś… Step-by-Step Fix

🔧 Option A: Temporarily disable Kaspersky (Quick Check)

⚠️ Do this only if you’re troubleshooting. Re-enable it afterward!

  1. Right-click the Kaspersky icon in your taskbar (bottom-right).
  2. Select “Pause Protection” or “Exit” (depending on version).
  3. Choose a time (e.g., 15 minutes).
  4. Go back to Foxmail, click “Send/Receive.”

If email works now, Kaspersky is the blocker — proceed with adjusting its settings (see below).

🔧 Option B: Add Foxmail to Kaspersky exclusions

  1. Open Kaspersky Internet Security.
  2. Go to Settings (⚙️ icon).
  3. Navigate to:
    • Threats and Exclusions → Manage exclusions.
  4. Click Add:
    • Path: Find your Foxmail.exe (e.g., C:\Program Files\Foxmail\Foxmail.exe)
    • Exclude it from all checks (or at least “Web/Network”).
  5. Apply and restart Foxmail.

🔧 Option C: Turn off Kaspersky’s encrypted connection scanning

  1. Kaspersky > Settings > Network settings.
  2. Find Scan encrypted connections or SSL/TLS traffic scanning.
  3. Turn it off or set it to “Do not scan encrypted connections”.
  4. Restart your PC and test again.

🧠 Bonus Tip: Double-check mail server settings

  • Make sure Foxmail uses correct:
    • Incoming server: mail.yourdomain.com
    • Outgoing server (SMTP): Same or mail.yourdomain.com
    • Check ports (POP3: 110/995, IMAP: 143/993, SMTP: 25/465/587)
  • Confirm you have internet and the domain mail.yourdomain.com is working.

If none of this works, Kaspersky might be expired or corrupted — try reinstalling or switching to another antivirus temporarily to test.
