OpenSMTPD: crypto_backend and encrypted queue

·414 words·2 mins
A few days ago, Charles committed the compress_backend API which allowed transparent deflation/inflation of envelopes and messages as they hit the queue. The compression code is executed before the queue_backend gets the data so that any queue_backend can benefit transparently from compression without having to add any code to handle it. Due to our design, this also means that if the queue_backend stores envelopes and messages remotely, then the compression will take place before sending and after fetching, the remote end only ever sees compressed data.

OpenSMTPD: I have no idea for that title, sorry

Howdie, Eric and I had planned a loooooong time ago to have a hackathon this week-end. However, some asshole piece of shit ran into my car while it was parked, made it unable to take the road and flee without leaving a note. Long story made short, I had to be at the repair shop this week-end to be able to get my car before end of September.

g2k12: OpenBSD hackathon

·904 words·5 mins
Yesterday, after nearly missing my plane by 5 minutes, I finally managed to make it to Budapest for g2k12, the OpenBSD general hackathon. While this is not my first hackathon, this is the first general one with many hackers working on all kinds of subsystems ranging from ports to network and kernel. It’s fun to see many people focused on improving different areas which you use daily, sometimes without even noticing, and doing it with as much fun as you are having fixing your own area ;-)

This is the first post of a series to illustrate and describe a “proof of concept” code by Charles, Eric and I. I will describe the features as they are implemented.

OpenSMTPD: src-address maps and spamhaus

First of all, I’d like to “thank” The Spamhaus project which forced me into hacking this feature in a hurry. See, I rent a server at online.net which I use for OpenSMTPD live testing and to run some experimental code before it hits the OpenBSD tree.
