Please help me with NDSMail

I downloaded NDSMail on my DS using the homebrew database that came with DSOrganize. I got the rss feeds working but I can't get it to work with my yahoo e-mail account. I looked up all the required information that needed to be put in the account settings in NDSMail and filled it all out. It still won't send or receive e-mail and on the main page it says the account I am using is the default account instead of my e-mail account that I entered the data for. It says I am using the latest version.
