How to Manage Spam Filters

Control spam delivery by configuring SpamAssassin and email filters on your {{COMPANY_NAME}} hosting.

SpamAssassin in cPanel

Enable SpamAssassin

1. Log in to cPanel.
2. Go to Email > Spam Filters.
3. Toggle Process New Emails and Mark them as Spam to ON.

Adjust Spam Sensitivity

1. Click Spam Threshold Score.
2. Lower score = more aggressive filtering:

- 5 (default) — standard filtering.

- 3 — more aggressive (may catch some legitimate emails).

- 7 — more lenient (fewer false positives).

1. Save.

Auto-Delete Spam

1. Toggle Automatically Delete New Spam to ON.
2. Spam emails scoring above the threshold are automatically deleted.

Warning: Be cautious with auto-delete. Start with marking as spam and review your junk folder regularly before enabling auto-delete.

Whitelist / Blacklist

2. Under whitelist_from, add email addresses that should never be marked as spam.
3. Under blacklist_from, add addresses that should always be treated as spam.

Email Filters (Custom Rules)

In cPanel

1. Go to Email > Email Filters.
2. Click Create a New Filter.

Tips for Reducing Spam

3. Use SPF, DKIM, and DMARC to protect against spoofing.
4. Train SpamAssassin by marking emails as spam or not spam.
5. Consider using a catch-all address only if necessary.
