Good morning WAMUGers

Can anyone advise what I can do about this message (below), it is not allowing my messages to go through to a Yahoo Group. I doubt that I have a virus. I have also tried sending to the group from .mac web mail and the web mail through Opera and I still get the same message. With thanks. Wendy
