Mac Mail OS 26.6.2, Smart Folders: I have three email accounts and want to look at all three inboxes and all three sent mail folders/mailboxes. When I use the 'any' filter and add all three inboxes, the @gmail inbox reverts to ***@me.com on save. In other words, it won't allow me to add the @gmail account.
Deleting and adding the @gmail account did not fix the problem.
