At http://drupal.org/project/[Your_project_name]/git-instructions you can read
Although it is standard practice to use a functional address, you can also use the pre-configured address [username]@[UID]-no-reply.drupal.org.
(replace [username] with your actual username and [UID] with your actual user ID number). However, after [UID] the hyphen (
-) is wrong and must instead be a dot (
.)! If you identify yourself with the displayed e-mail address, your commits will not be recognized as yours!
