First off, thanks for the awesome product(s)! I've been using your images for the past year or so.
I recently set up the gitorious native installer on a previously configured bitnami linux VM. I used the set up wizard to configure an email for the server to use. It went fairly smoothly, however when I would log in, I could add ssh-keys, but they never became 'Ready' (they weren't getting added to my authorized_keys file for the git user). The log indicated that it was unable to send smtp messages. Viewing the gitorious configuration file (config/environments/production.rb) it had two entries each for 'config.action_mailer.raise_delivery_errors' ('false' and 'true') and 'config.action_mailer.delivery_method' (':test' and ':smtp'). Upon commenting out the 'test' and 'false' entries, the server is now working correctly and I can add keys.
TLDR: You need to modify the native installer linux 64 script to comment out the two default mail settings when the user submits her own.
