Salmon, a Python Mail Server
From the page, some open-source drama:<p>> Salmon is a fork of Lamson. [...] Lamson was relicensed under a BSD variant that was revokable. [...] I read that to mean that I could make a contribution but then have said work denied to me because the orginal author didn’t like the colour of my socks. So I went and found the latest version that was available under the GNU GPL version 3.<p>Does anybody know the backstory here?
