Archiving emails to DEVONthink: behaviour when email moves to different mailbox

Reading the manual I am unclear on behaviour when Archiving emails from Apple Mail using the Import sidebar.

I understand that an email is only archived once due to its unique UUID. I think it is once per database and not once per mailbox (correct?).

I will illustrate with an example. If, say my mail account only consists of the following:

Inbox (mailbox)

  • email 1
  • email 2

Archive (mailbox)

  • email 3

and I archive, I understand DT3 will preserve the mailbox structure in the target database as set out above.

If at the next time I archive, my email client shows the following (because in the interim period I have received one more email (email 4) and I have moved email 1 and email 2 to the Archive mailbox):

Inbox (mailbox)

  • email 4

Archive (mailbox)

  • email 1
  • email 2
  • email 3

what will happen in my email archive database in DT3?

No doubt in my mind, email 4 will be added to the Inbox mailbox.

Will email 1 and email 2 now appear in the Archive mailbox (but not in the Inbox mailbox because they can only appear once in a database)? Or will they still show in the Inbox as they were originally archived?

I am not clear on the behaviour and would appreciate clarification.

Emails 1 through 3 won’t appear anywhere in the Import Email controls unless you switched databases in the Destination dropdown.
