The errors you got are exactly caused by the problem I explained you above. Yahoo and other servers are not accepting emails from your server because it uses a dynamic IP address.

This is a common problem and the reson why mailservers are normally not run on a dsl line. I listed the two solutions for your problem in my first post.

Take a look here on how to configure your email server to relay emails trough a external mailserver:
