Hey all,
Referring to a KB article (https://quickbooks.intuit.com/learn-support/en-us/customer-topics/3-solutions-for-when-customers-are...) it references a list of IP addresses to whitelist for receiving email notices (invoices, receipts, etc). I know that QBO is using SendGrid, but it appears that the IP list in the KB article is stale, since I've seen emails from 167.89.82.160 recently which is not in that list. Is there an updated list of IPs to whitelist? I have a customer that can't just whitelist all of SendGrid's IPs and we're having issues getting invoices to them.
Thanks!
