Always with the same

mailfrom

mailfrom

domain, as the one in that screenshot?

DDarkDeviL Always with the same `mailfrom` domain, as the one in that screenshot?

addisonOP•2/23/24, 5:02 AM

yeah always that domain, does it have to be the same domain as from? I assume not

DarkDeviL•2/23/24, 5:03 AM

Technically, no, they can be two completely different domain names (as well as the local parts, i.e. the stuff before

DarkDeviL•2/23/24, 5:06 AM

However, one thing I notice digging on that domain name:

You do not have a

_mailchannels

_mailchannels

TXT record, for their Domain Lockdown.

addisonOP•2/23/24, 5:08 AM

ohhh does mailfrom need the record too? ill give that a shot

addisonOP•2/23/24, 5:18 AM

there was an invalid mailchannels record but i swapped it with the valid one and still no luck

Aaddison ohhh does mailfrom need the record too? ill give that a shot

DarkDeviL•2/23/24, 5:21 AM

The "Domain Lockdown" thing was supposed to "fix" a problem where every Workers user, could pretend to be someone else's domain, and pass SPF checks, due to the wide

include:relay.mailchannels.net

include:relay.mailchannels.net

, so it was just a thought I got.

It wouldn't make any sense to apply that to the "

from

from

" (e.g. header

From:

From:

), but only the "

mailfrom

mailfrom

" (SMTP MAIL FROM) part, assuming that it exists, as that would be the one the SPF checks would be checked against.

addisonOP•2/23/24, 5:24 AM

seems like mail from still doesn't exist unfortunately

DarkDeviL•2/23/24, 5:30 AM

Can you try to shoot one or more messages my way, where you play around with

mailfrom

mailfrom

Alternatively, if you want a numbered tagging or so, if you take personal notes, you can do like:

sent one over

DarkDeviL•2/23/24, 5:34 AM

Exact same

SMTP FROM (envelope from, Return-Path, ...) as header From:.

addisonOP•2/23/24, 5:35 AM

this is what im sending over

DarkDeviL•2/23/24, 5:37 AM

It would be all guessing though, ... I wonder if they might have a documentation issue.

DarkDeviL•2/23/24, 5:38 AM

I mean, it goes with multiple distinct names such as SMTP FROM (envelope from, Return-Path, ...) ?

DarkDeviL•2/23/24, 5:38 AM

Can you try replacing

mailfrom:

mailfrom:

with

mfrom:

mfrom:

, and see if that makes any difference?

addisonOP•2/23/24, 5:39 AM

sent

addisonOP•2/23/24, 5:39 AM

their docs specify

mailfrom:

mailfrom:

but i cant find any examples that use it

DarkDeviL•2/23/24, 5:40 AM

Exact same

testing@

testing@

on both of them again.

DarkDeviL•2/23/24, 5:40 AM

And yeah, it's very limited (to none) that you find with the

mailfrom:

mailfrom:

, I just happened to find it at some point, which is why I suggested it to you earlier this month, as according to the documentation, that's the one we're after.

addisonOP•2/23/24, 5:41 AM

yeah you are where i got the idea from in the first place

addisonOP•2/23/24, 5:41 AM

definitely feels like a documentation issue though

DarkDeviL•2/23/24, 5:42 AM

envfrom:

envfrom:

could be tried as well though.

addisonOP•2/23/24, 5:43 AM

i sent another with envfrom

DarkDeviL•2/23/24, 5:43 AM

But yeah, either technical (as in incorrectly not doing at all), or documentation issue (such as documenting the wrong thing) would be what I suspect too.

DarkDeviL•2/23/24, 5:44 AM

Third time wasn't the lucky time here, as it's still just

addisonOP•2/23/24, 5:44 AM

is there some sort of contact for this? i've tried contacting mailchannels support before with no luck

DarkDeviL•2/23/24, 5:54 AM

If you have already tried MailChannels Support (cc @skoogeer @fiirhok), with no luck, I don't think so.

However, you could try assuming that the email (or whatever) was lost in transmission, and try again.

I've done so now, have a good night chat

charl.dev•2/23/24, 10:30 AM

Hi guys at 8:46 we had an issue where a lot of api calls proxied via a worker was giving 526 errors. When we updated the worker triggers to be more explicit, it started working

charl.dev•2/23/24, 10:31 AM

Has anything changed and would workers ever return a 526

charl.dev•2/23/24, 10:36 AM

We confirmed it was a wild card at the beginning

charl.dev•2/23/24, 10:37 AM

Has anything with the way the triggers work changed?

charl.dev•2/23/24, 10:49 AM

Ticket 3158394

charl.dev•2/23/24, 10:59 AM

Just want to know if something with triggers and prefixed with wildcard would be effected

Liam•2/23/24, 2:59 PM

Hey guys! Quick question:

I'm using a cloudflare reverse proxy for load balancing on API calls. Is there anything I need to explicitly do to make the load balancing work if I'm using the default template?

Can Cloudflare comment on this thread? TOS and all are good, clarifications would do wonders as well.

Hello, I’m Allie!•2/23/24, 4:17 PM

Assets must be stored on the Developer Platform(R2, Images, R2). Proxying a video through a Worker does not count, and thus would still be against the ToS

Santosh•2/23/24, 4:17 PM

Proxying a video srtored on R2, what would that fall under?

Hello, I’m Allie!•2/23/24, 4:17 PM

Though note, I am not a lawyer, nor am I Cloudflare Support, so for 100% certainty, I would recommend filing a ticket

Bulbasaur•2/23/24, 5:08 PM

The conflict is that they explicitly say in the previous blog post that a user serving video through workers was not against tos. So either something changed between those two blog posts, or there’s a mistake
