Mail filters
From HelpBase
Mail filters allow you to automatically perform different actions on email messages received by your email server. You can create filters based on the sender's email address, the recipient's email address, or the content of the message. Some of the possible actions are: discard, redirect, or move to a folder. For example, you could create a filter that automatically discards any email received from spamsender@cheapmortgages.com
User Level Filtering
Use the cPanel User Level Filtering module to create mail filters that are specific to a particular email account.
Account Level Filtering
Use the cPanel Account Level Filtering module to create mail filters that apply to all email accounts.
