How to make a mailbox containing not all but a selection of my inboxes?

Hi all,

I have a question. I have 3 mail accounts in my Mac mail. In the favourites bar on the left, I see "All Inboxes", but I would really like to have an option which shows the inbox of just 2 mail accounts.

I already tried to create a smart mailbox with either of the following criteria:

• Recipient contains email A
• Recipient contains email B

However this gives me all the emails, not only the ones that currently are in the inbox.

Therefore, I added the following criteria:

• Mail must be in "All Inbox"

However, this is not working because for the first criteria to work, I had to choose that it should contain any criteria not all, because otherwise the smart mailbox would only contain mails that are addressed to both mail A and B.

Is there any other way to get an overview of only two emails?

Thanks in advance!
