Well it seems Yahoogroups has a lot of bouncing emails confusion.
Though the emails’ members are also from yahoo.com, the error still happen.
I found more than 2,000 bouncing members in
http://groups.yahoo.com/group/syiar-islam/members?group=bounce
That’s quite big since the total members only 5,300.
