BT Yahoo are a nightmare for that, but if you need to send to those sort
of addresses you can do conditional routing, so addresses at the
freemail providers are routed via you ISP, and the rest goes direct.
That might get round your mail volume problem.

In Postfix that's transport maps, other MTAs I'm not sure.

As said, DNS A and reverse records that resolve to each other and SPF
will help.
