You should also list any other mail servers that accept mail for your domain. This includes email gateways and relays under your control. This can also include your ISP's mailservers, but if you do that, make sure to specify internal_networks separately and leave the ISP's servers out of that one.
Your ISP's mail servers, if they are accepting mail on your behalf, need to be included in your internal_networks too.
ANY server from an MX accepting mail on your behalf all the way to your SA machine need to be both trusted and internal.
