Ref-updated gerrit script to send emails via the mail command when commits are pushed directly to gerrit. Install into the gerrit/hooks directory and make sure it is executable. You may want to change the "gitblit.rams" url to point to your own source code viewing website (such as a gitblit server). This has been tested on Gerrit 2.5
