Yeah, many ISPs are wary of newer IPs with low volume. To avoid volume problems, you usually need to be sending from a server that delivers >10,000 mails a day. Also, check your logs. Yahoo uses the following graduation when dealing with a temporary blocked mail:
[TS01] -> [TS02] -> regular deferred message. (found in your logs) Your goal is to stay at TS01.
If you're experiencing significant deliverability problems, Yahoo wants you to stop delivering to them for four hours.
(We wrote an article about this a year ago, they've since then instituted feedback loops, which we employ in our deliverability service CritSend , but they still help you demystify some of what Yahoo's expecting from your server: http://blog.deliverability.com/nicolas_toper/ )
You've recieved some really great setup advice in this post and the owocki article as well. Keep a tight monitoring on your delivery feedbacks and spam folder clicks when you can by keeping watch through the feedback loops others have listed for you here.
Feel free to contact me if you need some help going through those logs for other deliverability items, they'll tell you a lot.
