Remove Duplicate Emails

You can control how Postbox handles duplicate e-mails that arrive in the Inbox.

Open the config editor.

Type "mail.server.default.dup_action" into the "Filter:" textbox and double click on the that row to change the value to one of the following:

  • 0 - the default value which is to leave the duplicate e-mails alone
  • 1 - delete the duplicate e-mails when they are received
  • 2 - mark the duplicate e-mails as read when they are received
