How do I remove Mail recipients from Mail in macOS Catalina?
When I go to create a new email and I type the first letter of someones name it automatically puts an email address I responded to like months ago. That email address is NOT in my Contacts and it doesn't show up in Previous Recipients. I can right click it and click remove but it comes right back as soon as I type that first letter. I have everything Siri turned off so it's odd that it shows Siri found in apps above the email address. This is only one example as it will place other email addresses in the TO: section if I type say an "s" it will put my cable companies email address in there.
