Trailing out the Email Beta System

Just been accepted on an account with the Email Beta. Setup and got an error when trying to send via outlook 365 account to this.

I have got the got the destination email for forwarding setup as well as catch all both going to the same email, which has been verified with green tick on cloudflare and email routing has green tick enabled as well after updating DNS records. I understand this is beta so not urgent to resolve.

Below is a copy not sure if this is the correct topic.

Policy violation or system error
How to Fix It
Check the “Reported Error” from the “Error Details” section shown below for more information about the problem. The error might tell you what went wrong and how to fix it. For example, if the error states that the message was blocked due to a potential virus or because the message was too large, try sending the message again without attachments.
If you’re not able to fix the problem, it’s likely that only the recipient’s email admin can fix it. Contact the recipient by some other means (by phone, for example) and ask them to tell their email admin about the problem. Give them the “Reported Error” from the “Error Details” section below.

More Info for Email Admins
Status code: 550 5.0.350

The error reported by the receiving server wasn’t specific enough to determine the exact nature of the problem. These errors often indicate the message violates a security or policy setting configured on the recipient’s email servers.

If the sender is unable to fix the problem by modifying their message, then it’s likely a problem that only the recipient’s email admin can fix. Try the following:

Check the error for information about the problem - The “Reported Error” returned by the external email server can be found in the “Error Details” section below. This error might tell you what went wrong and provide clues for how to fix it. For example, if the error states the message was rejected due a Sender Policy Framework (SPF) issue, then you’ll have to work with your domain registrar to correctly configure your domain’s SPF records.

Check the error for information about where the problem is happening - For example, look for a domain name like contoso.com. A domain name in the error might suggest who is responsible for the error. It could be the recipient’s email server, or it could be a third-party service that your organization or the recipient’s organization is using to process or filter email messages.

If you can’t fix the problem, contact the responsible party’s email admin - Give them the error code and error message from this non-delivery report (NDR) to help them troubleshoot the issue. For security or policy violation issues, it might be sufficient for them to just add your sending IP addresses or domain to their allowed senders list.

It’s likely that only the recipient’s email admin can fix the problem. Unfortunately, it’s unlikely Office 365 Support will be able to help with these kinds of externally reported errors.

Could you please share the domain you are using?

If you prefer I can help debug privately on Cloudflare Developers

pahicottages.co.nz

Thanks. I’m seeing an error on our side when trying to deliver the email.

The error is

permanent error (550): 5.6.0 Lone CR or LF in headers (see RFC2822 section 2.2)

Thanks for looking into guess that means your team is looking into this further I googled this and first result comes up with an issue on mailer side and thier example just like mine is linked with outlook 365 not liking the mailer setup. They had many solutions but given yours is built at such a large scale I am guessing a lot more investigation will have to be done to make sure fixes without causing other issues.

I can send an email from my Office 365 account → CloudFlare Email Routing → Gmail and the email gets there fine. I can also email from Office 365 → CloudFlare Email Routing → Office 365, and that email is also delivered no problem.

Maybe it is the delivery side then. It is sending though 365 routes on cloudflare then send to xtra.co.nz email. Which is New Zealand Telecom email one of if not the biggest local emails here.

Only made previous comment due to reference from quick google if there is anymore info I can provide to help let me know.

Just checking this is being looked to on your end. I have now tested this sending to GMAIL instead of telecom New Zealand xtra.co.nz email. And it works so guess that means there is some sort of block between this new service and Xtra domain. I will change this back to Xtra.co.nz address now so can continue to be tested.

Hi,
I’ve a similar problem.
I’ve enabled the use of Email Beta, and now nothing can enter in the inbox of the email.
Could you please help me ?

The error message i get is the following:
GMAIL:
Response of the remote server:
521 550 Upstream error

Thanks in advance for your help.

Could you please share your domain so I can have a look?

Yes of course,
My domain is titre.services.

And what do you mean by share ? ONLY giving the name or what ?
Thanks.

Correct. That’s all he needed.

Thanks, I don’t see anything wrong with that domain. Could you please send a test email?

@sven2 could you let me know if the initial error you posted is being looked into and I leave it setup like it is with that domain thanks. Just want to be acknowledged at least being looked into or queued ticket for being looked into at a later time and if I should leave the account setup like it is or changing things disrupts tests?

Sven, Here is the entire content of the returned email from sending to this domain
Yes sorry i’m French speaking and the result is partly in french.

We are seeing an error on our side when trying to deliver the email the upstream. Could you please DM me on Cloudflare Developers so I can share the error with you?

I’m seeing the same on [email protected] but only if the email is send from atec-it.at (hosted ad Microsoft).

mx.cloudflare.net
Remote Server returned ‘521 550 Upstream error’

Thanks tested again looks like same error. Will leave this with you to keep updating overtime. Here is another copy of error message currently I have setup that works well routing domain with rules to an office 365 that forwards on which works fine retaining original sender and reply to as a work around it is an improvement of going via a server but would be good to work direct on Cloudflare so open to keep trying overtime as upgrades and patches occur just let me know.
