Bulk delete of mail from Confluence mailbox

I'm using the mail archive in Confluence, which is a nice idea. But the mail archive has a lot of limitations.

One of them is bulk delete of mail. We really need to have a check box on every mail item and the possibility to delete all checked items. Including a select all button.

To use this function effectively, some filtering is also needed. So you could search and delete portions of all mails.
