I just thought I would echo BBennet's post. Had the exact same problem (can't send mail from ZD or from Yahoo Mail 2.0 web interface) and same error message and had to switch to Yahoo Mail Classic in order to send mail at all. This was this past wednesday. I spent over two hours on the phone with Yahoo support and by the end of the call they basically said, "Sorry, use classic mail for now and check back and see when the new 2.0 mail works. Nothing we can do." I seems too coincidental to me that these "unknown" errors and problems came after installing ZD. As both Yahoo mail 2.0 and ZD rely on the soap api. It looks like they have identified that soap is the issue above. Hopefully this issue can be solved quickly. Peculiar how Gmail works so well with a Yahoo! product(ZD) and the Yahoo! accounts don't seem to work yet.

btw; the Yahoo! tech i spent so much time with let it slip that he had heard that all yahoo mail was going switch and roll out via Zimbra by November. If this is accurate then we can assume the soap issues will be resolved soon. Giving ZD another try today.
