A subscriber network (business / residential) or so-called "cloud" networks are considered bad reputation, this often applies to the entire network and not to a specific IP address. It can be very difficult to get your mail through, even if you follow the recommendations wrt DKIM, DMARC etc.

You are right with that (especially with the network reputation), however the OP might replicate that "send direct" setup. I think configuring a lot manual routes instead of one (or a low
number) of smarthosts is getting unhandy really fast.

Thanks for pointing that out, I indeed changed the transport for my hubbed_hosts setup (some time ago). I like the approach of route lookup, because I try to avoid editing the config file for
possibly regularly changing parts (and it helps on updates, if the main configuration does not have to many changes).
