Smart Folders ability to share input lists

Reported by Keith | February 4th, 2016 @ 11:57 PM

When configuring a smart folder input under the "mailboxes" tab, at present it is only the output of a smart folder that is selected from the drop down menus.

It would be very useful if other options where available, such as the "input" list, and the "rejects" list.

This would make it much easier to build a cascading series of filters, where one filter can be configured to use as its input, the rejects list of the previous filter.

I think that this could potentially make things computationally more efficient.

    I'm not quite sure what you mean. Have you noticed that you can build a hierarchy of mailboxes with any/all (holding down ⌥ when clicking +). Or maybe you are talking about the Conditions pane?

    Mailbox "Mailing Lists" 
       Input (A) All Messages
       All messages with a list-id
    Output (B = the list of all messages with a list-id)
    Mailbox "Friends"
       Input (N) = (A) All Messages and None of (B) "Mailing Lists"
       All messages in my list of friends
    Output (C)
    Mailbox "To Sort"
      Input (A) All Messages
      and None of (B) "Mailing Lists"
      and None of (C) "Friends"
    Mailbox "To Read"
      Input (A) All Messages
      and None of (B) "Mailing Lists"
      messages tagged interesting

    When you build a hierarchy of mailboxes, and you select a smart mailbox, you are choosing the list of emails in that smart mailbox, its output, as the input to your next filter.

    I am suggesting that the input to Mailbox "Friends" be configured as...

    Mailbox "Friends"
       Input - B' ("Bee prime" the set of messages that are non-matching) 
        in other words the messages input to "Mailing Lists" for which the condition did not match
       i.e. "Mailing Lists" rejects.
    and mailbox "to read" be configurable as
    Mailbox "To Read"
       Input - N - the same set emails that was used as an input to Mailbox "Friends" 
       i.e. "Friends" input mailboxes/pre-condition-filter-applied

    Does that help or confuse further?

    • State changed from “new” to “bluesky”

    I'm not sure it's quite clear to me yet :-)

    Note that, internally, MailMate does not recompute any sets which happen to be identical. That is if you have two identical mailboxes then they are only computed once. The “None” method is not as intuitive as I would like it to be, but it appears you have figured out how to use it. Changes to how it works (the GUI) is a bluesky improvement for now.
