Email Routing Delivery Failed

I’m getting this error several times:

Unknown error: permanent error (550): 5.7.1 Service unavailable, Helo domain is listed in Spamhaus. To request removal from this list see https://www.spamhaus.org/query/lookup/ (S8001) [DU2PEPF00028D00.eurprd03.prod.outlook.com 2024-03-30T16:21:01.249Z 08DC4E51BB84918E]

Could anyone help me, thanks!

Do you still see this issue?

If yes, - what is your domain?

Hello! Yes I’m still experiencing this failure, my domain is cloudchainrepublic.com. I have to change the destination addresses from outlook to protonmail, disable the mx and txt record and reconfigure them several times, then the mails may forwarded successfully. Problem is I have about 190 mail addresses need be routing, so could you please look into it please? Thanks

I’m getting 36-40% failure rate

Same exact error over here for all the delivery failed issues I’ve manually checked going to outlook.com:

Looks like Cloudflare is in Spamhaus. Email delivery fails to iCloud as well.

I just set up email routing to forward from [email protected] to [email protected] address and all emails are bouncing with:

Unknown error: permanent error (550): 5.7.1 Service unavailable, Helo domain is listed in Spamhaus. To request removal from this list see https://www.spamhaus.org/query/lookup/ (S8001) [MW2NAM12FT052.eop-nam12.prod.protection.outlook.com 2024-03-31T19:03:20.318Z 08DC518DC780E21A]

I previously had email forwarding set up and working successfully at my previous registrar but am in the process of transferring my domain to Cloudflare.

What’s going on here?

I still have around 290 mail addresses in trouble now, this is very annoying

Same problem here. I had to back out of my plan to transfer my domain to Cloudflare for now. I couldn’t get it to work.

Same problem here.

i have this same issue and it is for every sender domain. none of them the sender domains are blocked by spamhaus so pretty much have denial of service since none of my email addresses work anymore.
and cloudflare providing no support and their status page states no email issues. all email flow stopped for me over 24 hours ago. i guess cloudflare not reliable so will need get rid of service.
pretty ridiculous!

same problem and been down for more than 24hr. all emails bounce and none of them are on spamhaus blocklist so this is internal issue at cloudflare

same issue. it has been down for more than 24hr and no way to get support. ROFL

it is time to more on to different provider.

Have you guys submit a request?

Same here

Same here, and protonmail is in the same issue too

Same problem here.
