To import all On My Mac mailboxes from Mail (macOS 10.14.6, EagleFiler 1.8.13), if all the mailboxes in the sidebar are selected, do the submailboxes have to be selected too or will they be copied along with the parent (and grandparent, etc.) mailboxes?
When importing from Apple Mail using the capture key, if you have no messages selected, EagleFiler will import the selected mailboxes and all their submailboxes.
Thanks for confirming – I should have remembered reading that in the manual.
