To install Typo I used the experienced user method. Meaning I installed it as if I was developping it. The setup is the same as Thinkosphere website. The code is inside a svn repository and the deployment is done thanks to Capistrano. 

Installation was pretty easy until it came to mailing capabilities which were not working. My old friend Google sent me to this blog : locomotivation.com/trackbacks The same tunings solved the problem. Indeed I am also working on Rails 2.x and this problem is due to a modification in Rails2.

However I add some more difficulties. Here is how you can lose 2 hours. The mailing was perfectly working in development environment but not in production. After 2 hours of Rails debugging into the mail sending low level code and a discussion with my host to get the smtp log, the solution appeared clearly : everything was working perfectly… but emails from the production blog were stopped by my spam filter while emails from the dev blog were not ! That’s a tricky situation.

So when working with mails do not forget your antispam !
