There's a conceptual issue with mailing patches from signed commits. Once your patch recipient goes to apply it to their branch, they are recorded as the "committer" identity of the new commit object. This would break the validity of any existing signature. This is likely the reason by the related git tools (format-patch, am) ignore this information. You may have also noticed that commands like git-rebase and git-cherry-pick will drop signatures from commits as well, since they are being replayed onto a different history, changing the commit data.
