Right now we are using the BitBucket "Email" hook. There is an alternative BitBucket "Email Diff" hook which also includes the diffs. However, I don't think this has the option of limiting the size of the diff so it might not be an ideal solution. We could have a separate commit+diff mailing list for those who want the full commit messages + diffs. The alternative is to use a POST hook and set up a script on a web server to receive the POST and turn it into an email (for example, this could be https://bitbucket.org/brunobraga/bitbucket-color-diff).
