I need some advice, as of three days ago I have not been able to receive emails to my Mac address, or send any replies, they just sit in the out box. 2017 desktop Mac, Version 11.6 Big Sur. I have two other email addresses, one Yahoo and also Google that are connected to Mail and which I use for various other reasons and I am receiving mail from each of these addresses but still unable to reply. I know there is an update to the next version but I am told when I try to install it that I don't have enough room to do so. I am wondering if there is something left over from this abhorted install that is causing my problem and if so what and where should I look.
Thanks. Kaye
