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"

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.

DarkDeviLOP•2/4/24, 5:18 PM

Last I heard about it was that such as e.g. the *.email*.email records, even though they might work, they were not actually supported.

I thought *.anything*.anything would work.

I mean a Snippet is a Worker, it is just free

HHello, I’m Allie!I mean a Snippet **is** a Worker, it is just free

dave•2/4/24, 5:20 PM

it's a big Worker lol

Hello, I’m Allie!•2/4/24, 5:20 PM

But it doesn't support anything other than HTTP afaik

Ddave it's a big Worker lol

Hello, I’m Allie!•2/4/24, 5:20 PM

Yeah, that's what the /j was for

HHello, I’m Allie!But it doesn't support anything other than HTTP afaik

dave•2/4/24, 5:21 PM

what else would you need to support other than HTTP?

HHello, I’m Allie!Yeah, that's what the /j was for

dave•2/4/24, 5:21 PM

eh for simple things it would work I think!

Ddave what else would you need to support other than HTTP?

Hello, I’m Allie!•2/4/24, 5:22 PM

All of the Worker tasks. Like a Workers free tier that isn't bounded by number of requests, but rather size of Workers/execution time

Hello, I’m Allie!•2/4/24, 5:23 PM

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.

dave•2/4/24, 5:24 PM

it does crypto in multiple places iirc

Hello, I’m Allie!•2/4/24, 5:25 PM

But yeah, you can't actually handle any events other than a

fetch

fetch

event in a Snippet, so it wouldn't matter.

Hello, I’m Allie!•2/4/24, 5:25 PM

Or, that is to say, you can't yet

Ddave wait is me using `email` some special allowed edge case that I guessed...?

DarkDeviLOP•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.

DarkDeviLOP•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.

DDarkDeviL If the Dashboard doesn't allow you to add "`.email`" as a sub-domain, I would **...

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

dave•2/4/24, 5:44 PM

but I think the catch-all case is reliable

Ddave but I think the catch-all case is reliable

DarkDeviLOP•2/4/24, 5:48 PM

My point is simply that I wouldn't suggest relying or depending on something that isn't officially supported, no matter how well / reliable it appears to be working.

DarkDeviLOP•2/4/24, 5:49 PM

And especially not if we're talking about it for mission critical things.

Chaika•2/7/24, 4:23 AM

Gmail. You can't send mail via Cloudflare except via Workers to your verified addresses or in reply to messages via email worker

Chaika•2/7/24, 4:23 AM

also iirc gmail like that always fails spf because the way it sends/alignment, been a while though

TTraffy How would you suggest to use cloudflare to receive and send email?

Chaika•2/7/24, 5:00 AM

Sadly, you don't. CF can't send mail like a normal email provider/solution. Sounds like you want a more traditional email setup like Fastmail, Google Workspace, ProtonMail that works with Custom Domains and can send and receive.

dave•2/7/24, 4:56 PM

we have outgoing emails from Gmail going through a Cloudflare Worker, but it's a messed up setup lol

Cchientrm.com ohm, sometimes MailChannel just doesn't send any email 😳

Unsmart•2/7/24, 5:09 PM

Afaik it will silently block any email they consider spam so the request wont error but not really sure on how that stuff works

chientrm.com•2/7/24, 5:29 PM

Uhm, I took some debug. It was my Pages CPU timeout when invoking bounded my email Workers

chientrm.com•2/7/24, 5:30 PM

I took some work around and now it sends email nicely again

Unsmart•2/7/24, 5:30 PM

That will do it too :LUL:

UUnsmart That will do it too :LUL:

chientrm.com•2/7/24, 5:31 PM

it's weird, they're just

fetch

fetch

from my Pages to bounded Mail Workers and from the Workerse to Mailchannels.
There was no heavy computation

chientrm.com•2/7/24, 5:32 PM

But when the request from my Pages -> Proxy express.js server -> Mail workers, it works fine again, no CancelledCancelled

chientrm.com•2/7/24, 6:05 PM

oh, just invoke via https url is fine, no timeout

KNOX•2/7/24, 8:29 PM

How do i set up a worker so that when a specific email address receives an email it gets sent to my server via an http post request?

Adi•2/8/24, 12:44 AM

Hey all, I'm sure this is a noob question, but is it possible / is there a walkthrough on how to send outbound emails via cloudflare?
I have email routing setup, but now I want to send emails out via that domain. Specifically looking for a low cost / free way of doing so.

Adi•2/8/24, 1:06 AM

I retract my question. For anyone else, this guide worked amazingly well - https://jay.gooby.org/2022/05/06/use-a-basic-gmail-account-to-send-mail-as-with-a-domain-that-uses-cloudflare-email-routing
