### AI overview

The article explains how invite systems can be abused for spam when users control organization names and platforms fail to limit invitation volume. It recommends sensible invite caps and monitoring for users who reach them.

### Source excerpt

Every time I think I've seen it all from spammers, they do something that surprises me. The ingenuity of bad actors is an interesting thing. I always wonder what sort of world we'd live in if their efforts were focused on good. What sucks the most is when they abuse something that's intended to bring people together. Case in point, an invite system. It exists to allow somebody the chance to get the rest of their team using a product or service. Invites wouldn't work if they said "You've been invited to platform" with no additional context. Typically the email states the name of the organization you're being invited to. "You've been invited to your organization name here". Where does that organization name come from? The user of course! And what happens if the user has ill intentions? They set the organization name to something like "Text 1-800-555-1212 for a good time", or something even sketchier than that. Generally speaking, these emails come through transactionally and from a generic email on the platform. If your system doesn't meter the number of invites, you have yourself a certified spam cannon! May as well set up an SMTP server without authentication, better known as an open mail relay. There's a few ways you can approach limits. Have a cap on the total number of pending invites? The spammer may delete pending invites to keep moving. Daily limits on total invites sent? Maybe they'll be okay with stretching their campaign over days? Probably not, most spammers are in the business of going as hard and fast as possible before they get caught. Occasionally somebody will fly below the radar, but I think that's more of a bug than a feature. Sane limits as to not get in the way of legitimate users tends to get you pretty far. Monitoring if/when somebody hits the limits is good too. Spammers usually won't write in to let you know they hit some limit. I say usually because there are some special folks out there that will come knocking.

### AI overview

The author describes exploring AI-assisted workflows for managing an email backlog. After trying self-hosted n8n automation, they turn to Claude Code and investigate using MCP to give it access to Gmail for identifying follow-ups and organizing information about companies.

### Source excerpt

I'm terrible at managing emails/DMs/etc. A lot of times it feels like trying to keep up is a full-time job in and of itself. Now that I don't have a job I finally have time to figure out a better workflow to manage life. I have a good workflow for writing notes and managing tasks in Bear, but my biggest weakness is staying on top of communication. What happens frequently is I'll have a backlog so big that I end up ignoring it, which is really bad as I miss out on opportunities or important emails. We now have AI as an incredible tool. I was always too busy to sit down and learn how to leverage AI to transform my life; it's so early and this space is super chaotic. However, I finally have time to figure out new workflows that use AI. My first attempt was to run my own instance of n8n on fly and setup some workflows for processing email. I got it working (and accidentally spammed my wife with multiple emails every hour, which she is still annoyed by), but I realized right now I don't need automations. I just need new tools to help manage my life. Next, I turned to Claude Code. I use it all the time while writing code, and I knew there was a way to extend it. So I thought of a specific use case: after announcing I left my job, I received a lot of emails from interested companies. Since I'm still dealing with some burnout, it's been difficult to stay on top of. How can AI help us here? I thought of a few questions: Which email threads should I follow-up on? Are there any important ones that I forgot to reply to? How can I more clearly see all these companies to help decide what my next step should be? I want to be able to clearly see a list of companies and info about them The first step is to give Claude Code access to my gmail. Writing a Gmail Skill to access email I've used tool calling before only when interacting with an LLM via an API. How do I give Claude Code, a product, the ability to read my email? It looked like MCP was the way to do it. Claude Code has an /m

### AI overview

This article explains how to configure leaky bucket, GCRA, and exponential rate limiters using a limit and a period. It describes average rates, burst sizes, forgetting behavior, and an email-server example for detecting spam.

### Source excerpt

Last year I wrote a pair of articles about ratelimiting: GCRA: leaky buckets without the buckets exponential rate limiting Recently, Chris "cks" Siebenmann has been working on ratelimiting HTTP bots that are hammering his blog. His articles prompted me to write some clarifications, plus a few practical anecdotes about ratelimiting email. mea culpa The main reason I wrote the GCRA article was to explain GCRA better without the standard obfuscatory terminology, and to compare GCRA with a non-stupid version of the leaky bucket algorithm. It wasn't written with my old exponential ratelimiting in mind, so I didn't match up the vocabulary. In the exponential ratelimiting article I tried to explain how the different terms correspond to the same ideas, but I botched it by trying to be too abstract. So let's try again. parameters It's simplest to configure these ratelimiters (leaky bucket, GCRA, exponential) with two parameters: limit period The maximum permitted average rate is calculated from these parameters by dividing them: rate = limit / period The period is the time over which client behaviour is averaged, which is also how long it takes for the ratelimiter to forget past behaviour. In my GCRA article I called it the window. Linear ratelimiters (leaky bucket and GCRA) are 100% forgetful after one period; the exponential ratelimiter is 67% forgetful. The limit does double duty: as well as setting the maximum average rate (measured in requests per period) it sets the maximum size (measured in requests) of a fast burst of requests following a sufficiently long quiet gap. how bursty You can increase or decrease the burst limit - while keeping the average rate limit the same - by increasing or decreasing both the limit and the period. For example, I might set limit = 600 requests per period = 1 hour. If I want to allow the same average rate, but with a smaller burst size, I might set limit = 10 requests per period = 1 minute. anecdote When I was looking after email servers

The article argues that the Dutch government should consider maintaining its email systems on government-owned servers when support for the current software ends on 14 October 2025. It describes Microsoft's promotion of migration to its US cloud and notes that nine ministries plan to acquire newer software to keep email on their own servers.

### Source excerpt

De hele korte versie: De kern van de Nederlandse overheid draait nu op eigen emailservers, in eigen beheer. Op 14 oktober 2025 verloopt de ondersteuning op de gebruikte software. Microsoft stimuleert sterk om dan alle email over te dragen aan de Amerikaanse cloud, met alle gevolgen van dien. Maar het is ook mogelijk (met wat moeite) om een nieuwe versie van de email software aan te schaffen, zoals 9 ministeries van plan zijn.

Open-Xchange maakt emailplatformen, met name voor telefoonmaatschappijen en internetbedrijven.

### AI overview

The article argues that Microsoft and other email security scanners now visit links in transmitted email and execute their JavaScript, including requests that trigger POST actions. It reports that this behavior can invalidate single-use passwordless sign-on and email-confirmation links, and discusses changing norms around email inspection and software behavior.

### Source excerpt

tl;dr: Microsoft and other email security scanners will visit the links in email you transmit, and run the JavaScript in those links, including calls that lead to POSTs going out. This used to be unacceptable, since POSTs have side effects. Yet here we are. This breaks even somewhat sophisticated single-use sign-on / email confirmation messages. Read on for how to deal with this, and some thoughts on how we should treat gatekeepers like Microsoft that can randomly break things & get away with it.

Welkom! Goed inzicht in ons parlement is belangrijk, soms omdat er dingen in het nieuws zijn. En soms juist omdat dingen (nog) niet in het nieuws zijn, maar er binnenkort wel besluiten over genomen gaan worden.
