https://support.google.com/a/answer/60764?hl=en SPF records are actually pretty useful for that, you can extract the outbound SMTP IP addresses for almost any largish ISP. When I was running a blacklist and wanted to exempt legitimate ISP outbounds, I tracked the IPs of the top providers by way of their SPF records.
