Thank you!!!  I was just about to reply and add that to the discussion.

For Quickbooks records, here are all the IPs in the article you keep asking us to allow. Nowhere in this list are the IPs that are being blacklisted. I would be more OK with adding the IPs if they were yours, but since it is a 3rd party emailing service it is not a good idea, it would be like doing a blanket allow for all gmail senders.
