This enables shaping based on MX hostname and domain name matching rules.
At a lower level, this is supported via two new options: additional_connection_limits and additional_message_rate_throttles that allow specifying arbitrarily scoped named limits and throttles, which in addition to allowing provider-based rules in the shaping helper, allow things like global or other more esoteric scoping of constraints.
