I do not know why I am receiving this as all my Paypal Payments seem to be going through fine. I only use this paypal account for my magento store too (no ebay or other selling channels). And on magento I am only utilizing express checkout right now. How would I find the source of the problem and fix it?
Thanks

You can try to disable this messages under PayPal account at:
Profile >> Selling Preferences >> Instant Payment Notification Preferences >> Edit IPN Settings >> Do Not Receive IPN Messages.
This way you can make sure if these e-mails are really coming from PayPal. If so, it means that PayPal is not getting success (200 OK status) reply in response to it's IPN notification and retrying it. This may happen due to some issues on your server, for example lost network connectivity for some small periods, that are not noticeable with normal browsing.
