DKIM with Postfix

[alecksievici]

Since some of us have problems with email being wrongly marked as spam on different servers (gmail/yahoo), i googled a little for postfix+dkim and stumbled upon these links:

http://dkimproxy.sourceforge.net/postfix...howto.html

since i am only a beginner in linux and do not have a test server i wondered if there is someone who could test dkim with postfix on an ispcp managed server and give us some feedback...
