We’ve just discovered that for the past two months, the forwarding address for our Hubspot inbox has not been working. All messages sent to our forwarding address receive a bounceback that says “554 5.5.2 No valid recipients.”
We have already double-checked that the address is correct, and that our organization is set to allow external forwarding (which is working properly).
Hey @EBerg2, thank you for posting in our Community!
Thank you for bringing this to our attention. We apologize for the inconvenience. Please double-check the forwarding address in HubSpot for any typos or formatting issues. Also, ensure that the address is correctly configured to receive emails.
The more information, screenshots, and details you can provide, the better I can advise on the next steps.
Good morning,
Thanks for your reply. As I mentioned in the OP, I’d already double-checked the addresses. Actually, I was just about to close this thread when you replied because it turned out the issue is with our email security suite rejecting the hyphen in the forwarding domain (hubspot-inbox.com). I’ve already opened a ticket with them and they’re looking into it, but it turns out this isn’t a Hubspot issue at all.
I apologize for the wasted post.
