I am trying to remove some old SMTP server accounts from my Mac, since they prevent me from sending emails from Mail.app. Every time I delete them from within Mail.app, they just reappear. I found the entries in Keychain as hidden entries, but deleting them give the same result - they just reappear.
I am running macOS Monterey, but I am pretty sure I had the same problem on the previous version. At the moment I am just using another non-Apple mail program, but I would prefer to use Mail.app.
Does anyone have any suggestions?
Thanks
