How can I deny a commit, in a client-side hook, if the user name/email is incorrect?

Is there any way I can access the commit author information (author name and email) from Git commit-msg hook?

I need to prevent commits which do not have the right email address (like [email protected]). I can do this on the server side with the pre-receive hook or the update hook, but is there any way to do the same on the client side?

Of course, I could run

git log -1 HEAD

in the post-commit hook and parse the output, but it's already too late, because the commit has already been created, at that stage. It can only serve as a friendly warning that the push will fail.

How about using a git var command? For example:

$ export EMAIL="[email protected]"
$ git var GIT_AUTHOR_IDENT | grep -E -o "<.+>" | sed 's,<,,' | sed 's,>,,'
[email protected]
$ unset EMAIL
$ git var GIT_AUTHOR_IDENT | grep -E -o "<.+>" | sed 's,<,,' | sed 's,>,,'
ja@AMDC689

Modify ~/.gitconfig:

[user]
        email = [email protected]

$ git var GIT_AUTHOR_IDENT | grep -E -o "<.+>" | sed 's,<,,' | sed 's,>,,'
[email protected]
