Mac Mail - BIG SUR - issues with mail on my mac
I used to have a folder called ALL INBOXES so all 4 of my email account messages would go into one INBOX. Now each email account has a separate Inbox, sent, spam, junk, etc. How can I have all my e-mail go into one INBOX and all my deleted messages go into one Trash bin. Same with Junk mail.
MacBook Air 13″, macOS 10.15
