My Mail account is giving me grief. A couple months ago, one account quit accepting the password to receive & send email. Now a 2nd (my main) account refuses to accept the password. I just changed the 2 passwords, but it still says no go. I know they are correct because the same passwords work fine on my iPhone, yahoo, everywhere else except Mail.
Any ideas as to what I can do to get my beloved Mail to again let me access my emails?
