Subject: [PATCH] util: Remove the unused function is_email_from_domain
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This commit pretty much reverts commit
04d4c4d45f3942a813b7f772737f801f877f4e64, it's just coded manually,
because "git revert 04d4c4d45f3942a813b7f772737f801f877f4e64"
resulted in conflicts. It's easier to just remove the single
function.
