I am the owner of a group, and I have received duplicated emails this evening. What is the cause?

I am the owner of a group. 3 weeks ago I received duplicated emails, and it didn%26#039;t happen again until this evening again. Now I received other duplicated messages (10 copies), copies of a single message I wrote. Is it because of yahoo or because of my host (which sends emails, which hosts my domain)? The duplicated messages are also on the group%26#039;s home page

That is just another Yahoo glitch like what happened before. It will %26quot;fix%26quot; itself.
