My calendar reminders are generating MAILERDAEMON errors because they are being sent to a long inactive email address and it is impossible to change that. The email address does not exist any longer but I have gone through all the settings and cannot find it anywhere. It was mentioned here: https://www.reddit.com/r/yahoo/comments/11xmivu/yahoo_calendar_email_remindershow_do_i_specify/ and yahoo-customercare asked for an email address of the person to send instructions - I think I need the same. Thanks in advance for the help.
