Recently (like, weeks ago) I investigated the big three BSDs for a small mail server project. OpenBSD was the first thing I looked at, I was especially interested in opensmtpd. Looking for documentation I stumbled upon [1] (note: Same aggregator, same domain. I consider that 'The canonical source for OpenBSD').
So that article praises the features of opensmtpd and then shows how to implement a filter. With this:
/* block idiots */ if (! strcmp(p->domain, "0pointer.net")) { filter_api_reject(id, 530, "You're not welcome, go away !"); return; }
At that point I shook my head in disbelief, labeled the author as person I don't want to read from again and moved on to NetBSD (and FreeBSD, still not sure with which one I'll go). OpenBSD's obviously for more elite persons and ad hominem attacks in random samples are .. I don't know. Funny? Cool with the users/the project? The Right Way™?
That project has lots of attitude problems.
