One likely scenario is that the person you're sending to (let's say john.doe@example.comjohn.doe@example.com) is forwarding that john.doe@example.comjohn.doe@example.com to e.g. a @gmail.com@gmail.com or @outlook.com@outlook.com/@hotmail.com@hotmail.com address, and that either Google or Microsoft is refusing to accept the message through Cloudflare.

DarkDeviLOP•12/1/23, 2:24 AM

If that happens, that the final destination rejects your message from Cloudflare, Cloudflare will push that rejection towards you, as "521 5.3.0 Upstream error".

DDarkDeviL Go to the <https://dash.cloudflare.com/?to=/:account/:zone/email/routing/overvie...

DarkDeviLOP•12/1/23, 2:25 AM

^ The domain owner of @example.com@example.com can then go in to Cloudflare like that, and search based on the message id, as seen from the end of the "521 5.3.0 Upstream error", to find out why the final destination rejected the message from Cloudflare.

DarkDeviLOP•12/1/23, 2:26 AM

It can be because the final destination doesn't like the content (e.g. believe the message is spam).

roccho•12/1/23, 2:54 AM

email-routing is available for "pages.dev" and "workers.dev" domain?

kian•12/1/23, 3:41 AM

Nope, you will need your own domain.

HJP•12/4/23, 7:42 AM

Hello! Is there anyone got the issue that Destination Address verified but the log from worker said that the Destination still not verified?

{
      "message": [
        "Error: destination address not verified"
      ],
      "level": "log",
      "timestamp": 1701156019743
    }

      "message": [

Cool to finally see subdomains being allowed woo, unless it's been a feature for ages and I haven't noticed hahah

only annoying think is that the root domain has to also be pointed to CF aswell :?

You can bork the walkthrough, and then only set up the subdomain, if you want to

Hello, I’m Allie!•12/15/23, 9:44 PM

I don’t remember what exactly I did, but otherwise, you can switch the MX records over for a second to validate, then revert them once the rest of the dash shows up

Hi, new to email-routing, does Cloudflare offer spam score by default? SPF checks etc.?

Sspace77along Hi, new to email-routing, does Cloudflare offer spam score by default? SPF check...

DarkDeviLOP•12/21/23, 4:45 PM

No, Cloudflare does not perform any content analysis in any way on the message, and as such, there won't be any "spam score".

DarkDeviLOP•12/21/23, 4:48 PM

If someone is trying to spoof the sender's domain as being a domain with a DMARC reject policy, such as for example

@google.com

@google.com

, Cloudflare will reject the messages unless you're able to satisfy the requirements for DMARC ( e.g. (DKIM pass + domain alignment) || (SPF pass + domain alignment) ), but that is only because Google has set the reject policy.

space77along•12/21/23, 5:06 PM

Good to know basic protections are there, thanks. Once I get my hands on your AI text-classification maybe the more sophisticated spams will be taken care of as well.

xeon06•12/26/23, 7:41 AM

Is it possible that the email router by default creates a plain text version of the email from the HTML if one isn't available? I seem to be getting plaintext out with things like

*test*

*test*

instead of

<strong>test</strong>

<strong>test</strong>

but can't find what's doing that on my end

xeon06•12/27/23, 11:46 PM

Also is it possible the status of the mail routes never loads on the dashboard? It's just a loading placeholder for both catch-all and custom addresses for me

Danny•12/28/23, 11:51 PM

Hi guys, anyone know what Error: original email is not repliable means?

Danny•12/28/23, 11:51 PM

I get it when

Danny•12/28/23, 11:51 PM

i send an email to the worker

Danny•12/28/23, 11:51 PM

it replies

Danny•12/28/23, 11:51 PM

and i send an email back

Danny•12/28/23, 11:51 PM

or try to, then i get that msg

xeon06•12/31/23, 12:43 AM

Are catch-all routes working to workers? I have one setup and getting back

550 5.1.1 Address does not exist. lER037lOKGee

550 5.1.1 Address does not exist. lER037lOKGee

, but my custom address works

xeon06•1/3/24, 4:51 AM

Looks like the dashboard interface is bugged but using the API I was able to confirm my catch-all route was disabled, and I also was able to enable it, and it works fine now

Alan Pear•1/4/24, 6:10 PM

If I set a catchall email for routing, and someone emails me at myemail@customdomain, is it possible for to respond from my routed email from myemail@customdomain?

Qantas94Heavy•1/5/24, 4:21 AM

Hi there, I've been testing using Email Workers and it seems I can only get them to work if the module is written in a certain format.

If I use e.g.

var foo = { async email() {} }; export default a;

var foo = { async email() {} }; export default a;

it will throw an error "Email Trigger not available to this workers". This is the default syntax used by wrangler deploy.

But if I use

export default { async email() {} }

export default { async email() {} }

from the dashboard it works fine. Is this a bug?

kian•1/5/24, 9:19 AM

Yes

user3470•1/5/24, 8:07 PM

I set up catchall worker, but it doesn't trigger when I send email to a random address at my domain, however the same worker works just fine when it is assigned to an address route explicitly. Is it a bug? And if it is, how to properly report it?

kingkong•1/7/24, 10:13 AM

hello i was wondering if someone can help me with this

kingkong•1/7/24, 10:13 AM

general-helpcatchall mail forwarding?

kingkong•1/7/24, 10:13 AM

which turns out is the same problem as the person above...

kingkong•1/7/24, 10:13 AM

thank you very much.

Tobias•1/8/24, 9:54 AM

@kingkong @user3470 If I remember correct. You can not have the same worker connected to custom addresses and catch-all at the same time.

Chaika•1/8/24, 2:44 PM

You can, I have one like that right now. It may be that it need some more time to sync, under overview the status should be "Enabled", not "syncing" or the same issue as the guy above email-routing

user3470•1/8/24, 2:45 PM

It's not connected to both at the same time.

user3470•1/8/24, 2:45 PM

Not in my case at least.

user3470•1/8/24, 2:46 PM

I don't have any status actually. It just doesn't load as it seems. See screenshot.

user3470•1/8/24, 2:47 PM

I wonder if that's the real problem

Chaika•1/8/24, 2:48 PM

I meant the Routing Status under the Overview tab, but if it's not loading that, could be an issue as well

user3470•1/8/24, 2:49 PM

Routing Status is «Enabled», and DNS is configured.
