How do I setup Spam Assassin and other email security measures?Set up your email security precautions. This was probably already done, except for setting any forwarding, when your hosting account was created. If so, no need to change it at all, but always check be sure:

1. Click on Mail icon in your CPanel. You will be taken to the Mail Manager Main Menu screen.
2. Click on “Default Address”; if it does not say “:blackhole:” in the box, click on the “Set Default Address” link at bottom of page. Then type exactly (without the quotation marks) “:blackhole:” in the empty box; click “Change”. Do NOT set this to “:fail:” because that will put more load on server resources, by having to return to sender… which is not even a real adddress most of the time.

3. Click on Spam Assassin.

4. Click on Enable Spam Assassin.

5. Once cPanel indicates the change was processed, click on Go_Back link to go back to Spam Assassin menu screen.
