Here is a guide on how to create a filter
Filters let you create rules for how your mailbox handles incoming emails. These rules tell mailboxes how to manage your email for you, allowing you to automate the process of organizing your inbox. To avoid multiple interactive emails which you will receive during Pribox functionality, you need to add a filter to your mailbox, so your inbox doesn’t get bombarded with our functionality emails.
Important: To avoid multiple interactive emails during Pribox functionality, create a filter on emails having words “MyPB” and label it as “Pribox”. Anything done beyond the provided information may cause disruption with our procedure.
