I just generated the private and public keys for my DKIM and it seemed to work.

is email routing purely sending to my own email?

Chaika•2/1/24, 5:13 AM

Yeah Cloudflare doesn't offer an SMTP server you can send out through.
Can send to verified addresses via workers and reply once via email workers on received mail, but nothing like a full email solution, it's a forwarder

villainy•2/2/24, 12:03 PM

trying to use the api to create an email route:
post body:

    "actions": [
        {
            "type": "forward",
            "value": [
                "testing@mydomain.io"
            ]
        }
    ],
    "enabled": true,
    "matchers": [
        {
            "field": "to",
            "type": "literal",
            "value": "myemail@fastmail.com"
        }
    ],
    "name": "Send to testing",
    "priority": 0
}

{
    "actions": [
        {

            "value": [

    ],

        }
    ],

Curious if the scenario of using cf email routing only on a subdomain is meant to be supported? ie keep your original mx for the root zone, and use cf only for the subdomain. I would have thought this would be one of the main use cases for subdomains. It works in some ways (incoming email is received), but two major blockers I stumbled into:

1.

.reply(

.reply(

does not work, you get a

mail from is not from the correct domain

mail from is not from the correct domain

, even though it is
2. sending emails via the worker binding is blocked by gmail servers with

This mail has been blocked because the sender is unauthenticated

This mail has been blocked because the sender is unauthenticated

, the error includes an SPF lookup of the root zone (?), not the subdomain. For more lenient gmail domains, like business domains, the email goes through, but received with a big red warning question mark in the contact photo

DDarkDeviL One thing is "appearing to work fine", something else is "supported" 😉

Hello, I’m Allie!•2/4/24, 5:09 PM

Isn't the docs thing just about the fact that you can't create a rule that only covers a subdomain?

Hello, I’m Allie!•2/4/24, 5:09 PM

So subdomain catch all could still be supported, just not "subdomain without root catchall"

Original message was deleted

dave•2/4/24, 5:17 PM

ahhh. Probably not the answer you're looking for, but we do the routing forwarding for the wildcard catch-all using a Worker.

dave•2/4/24, 5:20 PM

it's a big Worker lol

But it doesn't support anything other than HTTP afaik

I would assume so:

dave•2/4/24, 5:23 PM

does the 5ms count when you're awaiting on a fetch?

dave•2/4/24, 5:23 PM

if not, 5ms doesn't seem that bad.

Ddave does the 5ms count when you're awaiting on a fetch?

Hello, I’m Allie!•2/4/24, 5:24 PM

Afaik it is CPU time, though the docs are a little ambiguous

dave•2/4/24, 5:24 PM

Our catch-all email Worker takes ~6.6ms on average of CPU time and it could be optimized if we felt like it.

DarkDeviL•2/4/24, 5:42 PM

Actually, - my understanding of it comes from before subdomains were supported in the Dashboard, where my understanding was, ... that it was a "hacky workaround" that you shouldn't rely on, because it wasn't officially supported.

DarkDeviL•2/4/24, 5:43 PM

If the Dashboard doesn't allow you to add "

.email

.email

" as a sub-domain, I would personally still not consider it to be officially supported.

dave•2/4/24, 5:44 PM

it makes sense it works to hit the default catch-all Worker

dave•2/4/24, 5:44 PM

I agree I wouldn't depend on it for setting subdomain routing rules

{ "actions": [ { "type": "forward", "value": [ "testing@mydomain.io" ] } ], "enabled": true, "matchers": [ { "field": "to", "type": "literal", "value": "myemail@fastmail.com" } ], "name": "Send to testing", "priority": 0 }

{ "result": null, "success": false, "errors": [ { "code": 2007, "message": "Invalid Input: EmailAddress: must have address." } ], "messages": [ { "code": 2007, "message": "Invalid Input: EmailAddress: must have address." } ] }
