TL;DR: - greylisting is a sound idea - yet it is not really practical today - people tend to disable it or find work-arounds - SPF-aware greylisting makes greylisting usable again SMTP failures in a nutshell # SMTP is a fail-safe protocol which attempts very hard to ensure that messages do not get lost once they are in transit. Among the various mechanisms and requirements in place is the use of “Temporary Failures”.
TL;DR: - our CI was improved - a new OpenSMTPD release, 6.6.1p1 took place to deal with portable issues - multiple portability issues were adressed - new table API in the works - filter-rspamd and filter-senderscore were improved - filter-greylist proof-of-concept published - wrote 2 chapters for my book Got myself a pinebook pro # I got myself an arm64 pinebook pro:
TL;DR: - yay, surprise emergency hand surgery... - OpenSMTPD 6.6.0 was tagged and released, including portable version - Merged contributions to fix filter-rspamd bug with DKIM - Work resumed on 6.7.0 feature - An OpenSMTPD book is in the works How I landed in the emergencies # I accidentally cut my hand real bad early October and rushed to the nearest hospital. They had a look, told me it was superficial and required to be sutured, so I was out a few hours later with a few stitches and pain killers.
TL;DR: - I started writing this post a week ago but got interrupted by a baby, Jules - Spent MANY hours on writing OpenSMTPD-related articles - Enabled continuous integration in the OpenSMTPD portable repository - Managed to get rid of all the blocking issues for OpenSMTPD 6.6.0 release - Added some features and fixed a crash in filter-rspamd Welcome Jules, fork() completed # In my last report from August, I concluded not knowing if this report would be published on time.
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.
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 EDIT (2019-12-15) # A practical guide to set up a mail exchanger was published on this blog.
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 ! # As has become the habit, this report begins with a big thank you to my patrons, cited by contribution then alphabetical order.
TL;DR: - not much work outside of OpenSMTPD this week - OpenSMTPD portable builds with OpenSSL 1.1.x again - smtp-out reporting is working correctly on my laptop - wrote two filters that I'm actually using as you read this Shout outs to my patrons ! # As will become the tradition hopefully, this report begins with a big thank you to my patrons, cited by contribution then alphabetical order.
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:
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.
