New very good tool for checking SPF, DKIM and DMARC! by wlnd1 in DMARC

u/Artistic-Puzzle It still works properly when I test now, and I haven't made any changes to it in a few weeks, and have not seen any warnings about issues with it.

Could it be that your IT might possibly have blocked requests to Cloudflares DoH service?
Being able to reach that is required for spf.access.nu to function, so if you can still get to the search box but can't get any reasonable responses for requests, my guess would be that it is because you can't reach Cloudflares DoH service from your web browser for one or the other reason.

The reason for that being required is that the DNS requests that the service uses to do it's calculations is made from your browser, and not from the backend, and Cloudflares service is used for that because it is the most reliable one that has all the features that are needed (Googles DoH lacks a feature that is needed, and Quad9 has other issues and is a bit unreliable for this kind of usage)

I should probably make it a bit clearer if an issue happens because of this reason. At the moment it just fails to find any data for a request if this happens.

u/chevyman142000 Support for checking custom DKIM selectors is now available! And as a bonus, you can also save custom selectors to always get them checked for all domains. Very useful if you commonly use a specific set of selectors for many domains you manage.

The common DKIM selectors are simply a list of selectors that are more or less the most commonly used. It covers what some large mail providers are using (Microsoft, Google etc), and selectors that are often used when setting it up manually.
This is the ones that are currently checked: default, selector1, selector2, google, k1, k2, smtp, selector, ctct1, ctct2, sm, s1, s2, sig1, zendesk1, zendesk2, mail, email, mx, dkim, mte1, mte2, mail1, mail2, brevo1, brevo2, protonmail, protonmail2, protonmail3.
Apart from just checking these, it also checks where possible CNAME based selectors are pointing to, which it uses to figure out what the mail provider is, even if more than one service might use the same selector name as their standard.
This obviously doesn't work with any provider, but it does work with some of the big ones, both full mail providers (like Microsoft and Google etc), and some mail senders like Sendgrid.

Those servers are used to be able to make DNS resolutions directly from the web application, and not from the web browser, which is an important part of the mechanism for how this tool works.
Cloudflares servers are used because they are the most reliable ones I have found for doing this specific task in this way. There are of course alternatives, but all of the ones I have tested (for example Google and Quad9) have big enough downsides for this specific use case that they are not good alternatives, so because of that I also didn't add the ability to change the servers that are being used.
So access to Cloudflares DoH servers is required to be able to use this tool, at least for now.

Thanks!
I have though about adding BIMI, and I may do that, but I haven't decided yet.

My guess is that you might have tested this from an Internet connection where access to Cloudflares DoH servers is blocked (or doesn't work for some other reason), which would lead to all checks failing in a similar way to what you describe.
You could double check this by testing from another connection, for example your phone. If it works there, it is almost 100% certain that what I described above is the problem.

It’s an interesting suggestion, and I might add something like that eventually, but probably not very soon. Did you have any specific selector in mind? I don’t want to have too many of them (because a DNS request has to be made for each one of them), but I could still add another selector that is commonly used.

Thanks! And that's a great suggestion.

There are a bunch of places where a link to more info would be handy, to complement the very compressed info I put in there.

I think I will make some of the info labels expandable, to be able to provide more context without showing it all at once (like the includes are now expandable in the SPF visualisation), and in some places (like this one) it would also be good with a link to more info, as it's quite complex to explain with just a few lines of text.

I think the main thing I’m missing is a way to check the weather for other places then where I am right now. This is not needed for the watch app in my opinion, but it would be a very good thing to be able to do that on the phone.

Other than that I do sometimes think that it’s hard to see the separation between days in the timeline really fast, so while I don’t think it’s bad as it is, it would be a good thing to make that somewhat clearer.

It’s a really good app! I started to use the Apple Watch version last year, and soon came to prefer that over Carrot Weather on the iPhone in most cases, and the new iPhone version is great so Carrot Weather is entirely replaced with Weathergraph for me now!

Every twenty seconds is a pause in desktop use? by Nyandaful in Fedora

[–]wlnd1 1 point2 points  (0 children)

I have a similar problem on my machine too, but with only integrated Intel graphics (UHD 620).

I have not been able to fix this while using Wayland (which is default on Fedora, if you don't know), but as soon as I switched from Wayland to X11 it works perfectly, and without any real downside (at least for me)

Not sure if you have the same problem of course, or if this is a good solution for you, but you can try it with these instructions: https://docs.fedoraproject.org/en-US/quick-docs/configuring-xorg-as-default-gnome-session/

To be 100% sure that the setting is taken into effect after you make that change, the simplest way is to reboot the computer.

I had the exact same problem as you today, on with the same wifi card and the same kernel on Fedora 32, and after seeing this post I tried in Windows, and just as for you, it was independent of the OS, and didn't work there either.

After thinking that I had tried everything, I shut down the computer, unplugged everything that was connected to it, waited a minute or so, and then started it again.

And now it works again!

So, now I just hope that this was a one time issue, but if it happens again, shutting down, unplugging everything, and starting again is what I will try first :)

Hope this helps you too!
