How to delete an email filter?
To remove an existing mail filter, you will first have to select the mailbox the filter is created for. In the table below, you will find a list of all mailboxes, for which email filters have been created – all you have to do is to click on the one you wish to delete and then click on the icon in the "Delete" column.
A new window will pop, asking you if you are sure you want to delete the selected email filter. Click “OK” the delete it, or Cancel to leave it active.
