I think mail forwarders are still a good way to go. It's hard to predict how Internet providers will react to email running in their networks.
These days I have an ec2 at AWS for my mail server and use SES for outbound mail. I'm thinking of moving "receiving" back into my network with a simple chat forwarding service but keep SES for outbound. They handle all the SPF and DKIM things and ensure their networks aren't on blacklists.
