Handling `temperror`? · Issue #10 · cloudflare/dmarc-email-worker

I noticed Microsoft sends temperror sometimes; maybe we should show this in a different field, because it's a bit confusing to see <100% DKIM aligned, with 0 failures. <?xml version="...

They along Google and AWS were one of the ones that got hit by it, and disclosed it together

HTTP/2 Zero-Day vulnerability results in record-breaking DDoS attacks

The “HTTP/2 Rapid Reset” attack exploits a weakness in the HTTP/2 protocol to generate enormous, hyper-volumetric DDoS attacks. Cloudflare has mitigated a barrage of these attacks in recent months, including an attack three times larger than any previous attack we’ve observed

Tunnels use the normal proxy, unless you're talking about WARP Private Networking or arbitrary tcp with cloudflare accesscloudflare access locally

If you're using a simple public hostname, you're fine

That temperror literally means that that the DKIM that (hopefully) would have caused perfect DKIM alignment under normal conditions, ... wasn't really (considered) valid at the time.

As such, that specific message was falling back to the proper SPF pass (and alignment), to cause the overall DMARC pass.

Ddave https://github.com/cloudflare/dmarc-email-worker/issues/10

DarkDeviL•10/12/23, 11:20 PM

257 / 258 * 100 = 99.6124031008

So the 100% DMARC pass, 100% SPF alignment, 99.61% DKIM alignment is actually true, for 257 out of 258 messages having proper DKIM alignment.

So considering the title, - how would you handle that?

And as for the content, how exactly would you show that result, in a less confusing way :)?

Hi everyone, I’ve got a question regarding ZeroTrust. I have setup ZeroTrust with WARP in my organisation. Some users they see in their connections tab in WARP connection:WARP+ and some they see connection:1.1.1.1. How I can ensure all staff are connecting to WARP+ Melbourne ?

that error is esbuild so the Wrangler version is out of date, or they're doing custom builds and haven't marked cloudflare:cloudflare: modules as external

Without seeing your code and what the exact error is, there isn't much help anyone can offer. You should make a thread in #workers-help

asdfg.eth•10/13/23, 12:54 AM

my code is the same with the example https://developers.cloudflare.com/email-routing/email-workers/send-email-workers/#example-worker

mask•10/13/23, 2:03 AM

so here how I resolved the issue @asdfg.eth

Issue:

✘ [ERROR] Could not resolve "cloudflare:email"

✘ [ERROR] Could not resolve "cloudflare:email"

1 . edit the wrangler.tomlwrangler.toml for email configuration like the code below

[[send_email]]
type = "send_email"
name = "SEB"
allowed_destination_addresses = ["your_email@gmail.com"]

[[send_email]]
type = "send_email"
name = "SEB"
allowed_destination_addresses = ["your_email@gmail.com"]

then edit your script to be like the bellow```wrangler dev --remote --config src/wrangler.toml```because `--local` is no longer required and will be removed in a future version.

hope its help.

Is there an api to get statistics of your workers such as how many times they have been called without accessing the ui?

Hello, i have domain A (notify.domainA.com) that cnames to domain B (notify.domainB.com).I had to enable custom hostnames so that they can comunicate correctly, that is ok, but when domain B (notify.domainb.com) is a zero trust tunnel, the solution does not work. If I call notify.domainB.com it works, but when calling notifu.domainA.com it does not work and goes to another subdomain
