There's a vague thread over here I found with someone having possibly the same error, suggesting they also need MX records. Does that sense?

It looks like yeah the support thing I linked seems to suggest the email you send from must be able to receive even if you dont read it. Not sure if theres fake mx records you can put to just null route them or not

James•8/13/23, 9:24 PM

Not directly solving your problem, but I would recommend avoiding MailChannels and using what Unsmart linked, or some other service like Amazon SES, Sendgrid, Postmark, etc.

There are a lot of security implications and their responses to the whole ordeal have been very undesirable. Further reading:

Yeah, I figured there was a potential for abuse, which is why I put off trying to create an spf record until a way of locking down the sender was introduced.

A null MX record is surprisingly a thing! You just enter

Zoho's ZeptoMail is also a great choice. It's what I use.

Postmark has amazing deliverability and I'll never use anything else. I even pay extra for our marketing software to route emails through Postmark

they were cached requests, so no

I’d recommend following https://community.cloudflare.com/t/community-tip-fixing-error-524-a-timeout-occurred/42342.

James•8/14/23, 2:18 PM

But realistically, the solution here is really going to be to fix/improve your origin server to respond faster.

James•8/14/23, 2:19 PM

The max timeout of 100 seconds? You could probably get it increased with an enterprise agreement, but that’s about it as far as I know

How should you go about uploading a folder to R2 from wrangler or another CLI tool?

James•8/14/23, 3:17 PM

I would recommenad

rclone

rclone

for something like that

valkyrie_pilot•8/14/23, 3:17 PM

does r2 support that?

oh cool, it does

rclone and github actions, oh dear

So rclone mostly works, but it creates a new file when i try to specify a folder in the bucket.

There is no potential for spoofing your domain on MailChannels now that Domain Lockdown is required, so I'm not sure why you are advising people to go elsewhere.

James•8/14/23, 6:20 PM

Was there an announcement for Domain Lockdown now being required? This seems to be a new change.

James•8/14/23, 6:21 PM

I'm very happy this is now required, but considering how easy it is to still spoof many of your customers for a tiny price, and the general response from MailChannels to this whole ordeal, I'm still not comfortable recommending MailChannels, sorry

skoogeer•8/14/23, 6:30 PM

We check whether your email sender domain has an A, AAAA, or MX record. If it has none of these, then we generate the SDNF rejection error. Make sure the sending email address - the one specified in the "from" parameter in your API call - successfully resolves.

skoogeer•8/14/23, 6:54 PM

The ARC support is intended to improve security by adding a signature verifying the integrity of the headers that we saw when the mail was submitted to us. It's not intended to help bypass any receiver security measures. I think that the DEFCON researcher is misguided in his interpretation of ARC being some kind of backdoor. It's very much not that.

I think that the DEFCON researcher is misguided in his interpretation of ARC being some kind of backdoor.

That was not the impression I got from reading the slides. I understood it as "This is another thing that MailChannels does that makes it easier for abuse to get delivered", which seems accurate

James•8/14/23, 7:47 PM

Agreed ^. You need to address how you're planning to fix the underlying issues brought up in the entire talk @ttul

archon810•8/14/23, 8:12 PM

Hi,

Now that firewall rules have become custom rules, we can finally specify a custom HTML block response per rule, which is fantastic.

However, a few things could be improved.

There’s no way to quickly customize just the block reason because custom HTML replaces the whole block page. Ideally, there’d be a way to use an existing CF template and just customize the block reason.

To work around that, I pulled HTML from CF’s existing block page and made a few tweaks, including specifying a custom reason. Upon submitting the HTML, I saw that the response limit is a measly 2048 bytes, which isn’t even enough to serve CF’s own block page. I had to cut it down severely. Ideally, the limit would be a bit higher - at least 4096 bytes.

How do we use dynamic fields in responses? I tried using ::RAY_ID:: and ::CLIENT_IP:: per https://developers.cloudflare.com/support/more-dashboard-apps/cloudflare-custom-pages/configuring-custom-pages-error-and-challenge/, but they just got output verbatim instead of their dynamic values.

Dubz•8/14/23, 9:44 PM

Is there a way we can transfer domains from one account to another if it's registered on Cloudflare, without renewing/transferring? I'd imagine that could be an issue being the same registrar, but support may be able to do it?
