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

Question

I am the owner of a group. 3 weeks ago I received duplicated emails, and it didn'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's home page

Answer 1

That is just another Yahoo glitch like what happened before.  It will "fix" itself.
