Step 1 - Log In
Log in to your cPanel area. You will usually find it by adding /cpanel to your domain name - for example, www.yourdomain.com/cpanel .
Step 2 - Go to SpamAssassin
Click on the SpamAssassin icon.
Step 3 - Enable SpamAssassin
Click Enable SpamAssassin to begin filtering spam.
Once you see the confirmation message above, you may log out or click Go Back to adjust more SpamAssassin settings. SpamAssassin will now add [SPAM] to the subject line of all incoming messages suspected of being spam. The label makes it easy to identify spam and can also be used by your email program's filters to automatically transfer suspected spam into a separate folder; consult your program's Help section if you need help adding an email filter.
Step 4 - Optional: Permanent Deletion
To have SpamAssassin permanently delete all suspected spam messages, click Auto-Delete Spam. We recommend leaving Auto-Delete disabled, since at least some legitimate emails will be mislabeled as spam and will then be lost forever.
If you opted to have all spam automatically deleted, then may want to adjust the filtration level. Select a number between 1 and 10 to specify how aggressive your messages will be filtered. A higher number means more spam will be caught by the filter, but it also increases the likelihood of legitimate messages being misidentified. In general, start with the default setting (5) and then increase or decrease it depending on (a) how much spam is still making it through the filters (i.e. try using a higher number) and (b) how much legitimate mail is being flagged as spam (i.e. try lowering the number.)
Step 5 - Optional: Adjust Filtration Level
If you have Audo-Delete disabled (see Step 4) and would like to make the spam filters more or less agressive, first click on the Configure Spam Assassin button.
The default score is set to 5. In the required_score field, change the number to a higher one (i.e. 6, 7, 8 or 9) to make the filters less aggressive and allow more messages through the filter (setting it to 10 will let ALL mail through.) Conversely, change the number to a lower number (1, 2, 3 or 4) to make the filters more aggressive when targeting suspected spam (setting it to 0 will flag ALL mail as spam.)
Finally, scroll to the bottom of your scren and click Save.
