Solution: Anyone who has their notifications going to Yahoo needs to set their SpamGaurd to "Save SPAM for 30 days", save the changes, and then wait for a response from APC. It will shoot the APC email into the SPAM folder. From there, simply open the message from APC in the SPAM folder and click on the "Not SPAM" icon in the message. At that point, Yahoo will automatically move all notifications from APC into your normal inbox.
I hope that this will help! Sanjay and Susie: Thank you!!!
