You misunderstood me. It is not that Yahoo automatically trusts high volume senders, it is that Yahoo need to see a reasonable sample of email from a sender before making decisions regarding how to treat that email. In your case, one possible reason for the delays could be that they do not see enough volume from your IP address to make a determination that your email does not need to be delayed. Since individual emails are probably not experiencing delays, you could just route the list traffic through Amazon SES (or similar) - thus keeping your independence as a mail server operator. Again, tiny volumes may not be the cause of the issue, I'm just speculating based on your assertion that you are doing everything else correctly.
