When only_use_best_mx_for_relay_domains is set to true, only the lowest numerical priority MXs are used when sending to domains listed in bounce_domains or relay_domains; others are ignored. If this value is set to false, all MXs will be used. The default value is true (however, this option is typically set to false in the default ecelerity.conf file).
