Here I will collect the things I know or find out.
I'll write about Ubuntu/Arch Linux, Windows, Bash and Perl Scripting, Virtualisation and whatever else that could be interesting.
All I'm going to write here is tested by myself. I don't give a warranty of the functionality on other systems.
If there are questions, suggestions or something else feel free to send me an mail.
I recently installed a DokuWiki on Ubuntu 12.04 Server Edition. But after adding BlogTNG I only get an Error 500
To use Seiichiros mail-setup with Ubuntu 10.04 I have to make a couple of changes. I will describe here only these changes. The complete setup can be found on Seiichiros Website.
The Ubuntu 10.04 standard repository doesn't offer a package for dovecot2. Dovecot1 doesn't support lmtp and the antispam plugin has a bug. With use of an additional repository the configurations can be made as described by Seiichiro. I had to made a few adjustments and I integrated support for ClamAV.
