Followed closely proofpoint essentials documentation, using the Microsoft 365 Integrated Deployment option.
DKIM/SPF/etc. All set up correctly. Rules enabled.
Anyone else running into this? Based on their automated deployment it would be everyone using proofpoint email essentials at this point?
Did I miss a step?

I have - many, many times - filled out the form for getting our IP removed from Proofpoints' blocklist/blocklists. We are not on any other blocklist. Our traffic is legitimate and we have multiple layers of protection on the server and use rspamd to block spam. We do not send bulk email from this server.
I have had zero success in getting proofpoint to respond to any contact. I am very frustrated and I would like to know if anyone can assist in helping me get traction in getting them to remove the block.
Can anyone please help point me in a direction that can get this done? It's been months of filling out the removal request form with zero response.
I am a current Barracuda Email Gateway Defense customer and looking to move away from them. Barracuda does not provide descriptive SMTP delivery codes (IE: 5.7.1), only basic 250/550. Rejected emailers are not being informed why their email was rejected, causing much frustration (I reject 237 file extensions, would be nice if the email author knew it was because they attached a exe!).
Does Proofpoint offer descriptive delivery rejection information?
