Normally my Rejector account forwards to my main account so that I don't have to log in to two accounts. I woke up thinking today, "Gee, it's been a long time since I got email as the Rejector," and individually logged into that account, only to discover - to my horror -that there were 669 messages for me.
Apparently Yahoo!Plus didn't auto-renew the forwarding at the end of the year, i.e. late October. So you may get a really, really, really delayed response to your email. Sorry.
