Boxtrapper:
The cPanel BoxTrapper allows you to activate e-mail verification for those not on your white-list. Any mail address not placed on your white-list will be required to send back a verification mail to ensure that they are not a spammer. This function can be quite helpful in preventing automatic mailings that you do not wish to receive from reaching your inbox.
Steps:
1. To access the Mail Menu, click on the icon above the word Mail on the main screen of your cPanel interface.
2 Click on BoxTrapper Spam Trap.
3 To enter the BoxTrapper menu, click on the word Manage.
4 Click on the button labeled Enable to enable the BoxTrapper.

Spamassasin:
Spamassasin is a software used to check e-mail messages contents, give it a score, and find it as spam if the score is above the set limit. We can blacklist as well as white-list the IPs to allow or deny the messages.
The spam score is set to 5 as default, which decides whether the message is spam or not; as the spam score becomes less, there is more chance to detect a message as spam. These are done based on a complex algorithm (Some parameter is checking message contents and links and comparing which is more and setting the score according to that).
If you want to allow all types of messages from particular IP addresses, then WhiteList it.
If you do not wish to allow any messages from specific IP addresses, then BlackList it.

Follow the same steps in Account level filtering to create the user level filter.
