 That's possible but I wondered about what if a user changes their email TO
 an @example.com or .invalid address after installation for some reason and
 then changes is back - that's still result in the emails as the email
 functions are added as default filters.

 One other thought I'd had was improving the core is_email() function and
 only sending the email if that validates however it seems DNS checks were
 moved from that filter previously and PHP filter_var() is not enabled on
 all installs.

 I guess this is a careful balance to ensure we do send emails as much as
 possible without sending ones doomed to fail from the start, or maybe
 accepting failure is better than non-sending so just leave it.
