How prevent deleting copies of message I email to myself?
I use macOS Catalina's Mail app as IMAP client to GMail. Often when sending a message from Mail to somebody else, I cc myself so as to save the information. But when I go to the Sent folder in Mail and delete what I sent to the other party, then the copy cc'd to me also disappears.
How can I prevent that cc'd copy to me from disappearing (while still being able to delete from the Sent folder)?
