How to Set the Default Sort Order

To change the default sort order for all folders, please follow these steps. Note that these settings may not be compatible with future major versions of Postbox.

  • Go to Preferences | Options > Advanced > General and click on the Config Editor button.
  • Search for:
mailnews.default_sort_order
mailnews.default_sort_type

The sort order values that can be changed are the following:

1 = Ascending
2 = Descending

The sort type values that can be changed are the following:

17 = None
18 = Date
19 = Subject
20 = Author
21 = ID (Order Received)
22 = Thread
23 = Priority
24 = Status
25 = Size
26 = Flagged
27 = Unread
28 = Recipient
29 = Location
30 = Label
31 = Junk Status
32 = Attachments
33 = Account
34 = Custom
35 = Received

Change the values and restart Postbox.

Note also that changing these values will only apply to folders where the sort order has not already been set. For those folders, the sort order must be set manually.
