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.

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

Cancelled

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

DarkDeviLOP•2/8/24, 2:03 AM

"Amazingly well"?

I strongly suggest that you look at:

email-routing

https://community.cloudflare.com/t/reply-from-a-custom-address-email/455857/7

Adi•2/8/24, 2:05 AM

Yes you're right. It's not a perfect solution, and I definitely noticed the "sent via gmai" mark that never leaves. But I suppose this is as far as it can go with the way email routing works right?

DarkDeviLOP•2/8/24, 2:05 AM

And then remove the "a mx include:_spf.google.coma mx include:_spf.google.com" part from your SPF.

: Cloudflare HTTP Reverse Proxies will never send on your domain's behalf.

mxmx: Is pointing to Cloudflare's INBOUND mail servers, they do NOT send OUTBOUND and should not be listed in your SPF.

include:_spf.google.cominclude:_spf.google.com: The "trick" will always authenticate as the @gmail.com@gmail.com, and expose the real Gmail address. Since the SPF is done on gmail.comgmail.com, you're overauthorizing by having include:_spf.google.cominclude:_spf.google.com, which - depending on the eyes looking at it, is a security issue / risk.

DDarkDeviL And then remove the "`a mx include:_spf.google.com`" part from your SPF. `a`: C...

DarkDeviLOP•2/8/24, 2:08 AM

That "send via gmail" is due to the authentication marks being done on @gmail.com@gmail.com, getting it away would require a proper email service, that would authenticate using your own domain.

DarkDeviLOP•2/8/24, 2:09 AM

None of the free hacky workarounds such as this would do so (... 100%).

Adi•2/8/24, 2:09 AM

Makes sense, so there's basically no alternative to actually purchasing or setting up an actual email service.

DarkDeviLOP•2/8/24, 2:09 AM

In fact, even some paid ones may not even allow you get such things completely away.

DarkDeviLOP•2/8/24, 2:10 AM

And nope, the stuff i mention in e.g. the Discord link above - about missing alignment

DarkDeviLOP•2/8/24, 2:11 AM

1&1/GMX/Web.deWeb.de and others announced three (or four?) years ago I believe, regarding "no-alignment = slow entry"

DarkDeviLOP•2/8/24, 2:11 AM

Google ramped up their requirements in Oct or Nov 2022

DarkDeviLOP•2/8/24, 2:11 AM

And lately, both Google and Yahoo ramped them up here per February 2024.

DarkDeviLOP•2/8/24, 2:12 AM

You aren't able to satisfy the latest February 2024 requirements with a hacky workaround set up like this.

DarkDeviLOP•2/8/24, 2:13 AM

Although it appears Google and Yahoo claims it is affecting senders with 5.000 or more messages, ... the mystery remains: What exactly are they counting the 5.000 messages on?

DarkDeviLOP•2/8/24, 2:14 AM

Google's mail servers itself send quite a bit more than 5.000 messages per day, so Google might only need 5.000 different users, sending one message per day, to hit you negatively...

DarkDeviLOP•2/8/24, 2:15 AM

-> Due to the lack of proper email authentication

Adi•2/8/24, 2:15 AM

Damn

I suppose, do you have a recommendation for cost efficient email?

Adi•2/8/24, 2:15 AM

Also, thanks for taking the time to explain in so much detail, it's very appreciated

DarkDeviLOP•2/8/24, 2:19 AM

Well, I have always been a happy self-hoster of email, and are still doing so in 2024, and doing so very well and problem free.

DarkDeviLOP•2/8/24, 2:20 AM

The vast majority (if not all) that I've seen complaining about self-hosting email not working properly, is literally always due to their own failures to make proper choices, - e.g. many of them are choosing bad providers that continuously house spammers, or otherwise lack proper "abuse handling".

DarkDeviLOP•2/8/24, 2:20 AM

Or otherwise fail to configure the stuff properly, - although it isn't harder than e.g. running your own web server or so.

DarkDeviLOP•2/8/24, 2:21 AM

Re. providers, you definitely want to avoid the cheapest cloud providers that are popping up on the first few pages of Google searches, - if you go a such way.

DarkDeviLOP•2/8/24, 2:21 AM

That said, I'm not always saying that self-hosting will be the way to go.

DarkDeviLOP•2/8/24, 2:23 AM

"Cost efficient" is very depending on your opinion of it though, $10/month could be cheap for one, but too expensive for another and so on.

DarkDeviLOP•2/8/24, 2:26 AM

https://mxroute.com/ offers yearly packages, depending on your storage requirements

DarkDeviLOP•2/8/24, 2:30 AM

(And even seem (from time to time) to offer a life time package for low volume users.)
