post2mail plugin

Hello !
I’ve also problems to find a working plugin to mail someone when a new post is added in WP 1.5. I have tried to use the “Update Service” but it seems that it won’t work with an email address. Is there a plugin which will be working with WP 1.5 ?
I already tried these without success:
