Those aren't big numbers and it shouldn't bother your server much even
if they were orders of magnitude higher... Why not just ignore it?
Or do you want to improve the user's experience by getting a DNS in
their inbox where they might see it - which is what would happen if
the server where they submit didn't know the user list?
