First of all, as usual, a huge thanks to the people supporting me on patreon. Not all of my patrons wanted their names listed, and keeping track of who should or not be listed is tricky as people use aliases. [Read More]

TL;DR: - NO TL;DR: this time, I spent hours writing, you should spend minutes reading. - OK... I explain in WAY TOO MUCH details how to setup a mail server EDIT (2019-10-26) OpenSMTPD 6.6.0 was released today, the article was updated to reflect that it applies to the current release and no longer a development version. Wow, that was unexpected In a previous article, I explained why I think the “mail is hard” myth is unfounded and why I think people shouldn’t be discouraged from running their own mail services. [Read More]

TL;DR: - Mail is not hard: people keep repeating that because they read it, not because they tried it - Big Mailer Corps are quite happy with that myth, it keeps their userbase growing - Big Mailer Corps control a large percentage of the e-mail address space which is good for none of us - It's ok that people have their e-mails hosted at Big Mailer Corps as long as there's enough people outside too Disclaimer ** OBVIOUSY, I’M ASSUMING YOU ARE A SYSADMIN, WITH TECH KNOWLEDGE, WHO KNOWS BASIC NETWORKING, HOW TO SETUP SERVICES, HOW TO ADD A DNS RECORD ** [Read More]

Tl;DR: - small inprovements to the fion window manager - plakar is a backup utility I wrote a long time ago that I will share - tons of opensmtpd stuff, mostly filters and issues handling Shout outs to my patrons !

TL;DR: - started working on FION, a static tile window manager - revived BPG, a PGP parser - converted OpenSMTPD to libtls - wrote a library to make writing of native C OpenSMTPD filters easy - started writing a filter-rspamd Thanks to my patrons ! First of all, a huge thanks to my first patrons: Bleader Raton Diego Meseguer Mischa Peters Vegar Linge Halaand I have recently switched to a 75% part-time schedule at work so that I can spend a “free” week each month working on my own stuff, mostly opensource, without any kind of pressure: no one knows what I’ll be working on and no one but me gets to decide how I’ll spend this time.

TL;DR: In this post I explain crudely how ca.c works and changes to OpenSMTPD related to ca.c I wrote an ECDSA privsep crypto engine I did some EEG work too This is the first report I will now switch to a monthly report of my tech activities on this blog, and this is the first post in that new format. The focus will be put on interesting topics, not necessarily every single commit and bug fix I do (ie: won’t mention LMTP bug fix here), this depends on the amount of slacking that ocurred during the month and how much I want to cover it up :-) [Read More]

TL;DR: Way too many things happened in a six months timeframe. This post won't need a TL;DR as I'll keep it short. Generalized anxiety disorder and alexithymia. Late 2018, I’ve been diagnosed with generalized anxiety disorder and alexithymia a couple weeks apart. The anxiety disorder didn’t really come as a surprise as I know very well the traumatic experience that led to the disorder. It’ll still take a lot of hours of hypnosis to continue cleaning up trauma after trauma, but taking care of it and releasing some of the traumas has improved considerably my anxiety. [Read More]

TL;DR: regex table lookups were introduced for builtin filters. After a few weeks of working solely on filters, I wanted to work on something else. Using the same mechanism, all match criterias using tables can support regex. K_REGEX lookups The table mechanism is used within OpenSMTPD to perform all kinds of lookups. Recently, while working on builtin filters, I introduced the K_REGEX lookup type allowing tables to serve regex(3) patterns. [Read More]
