I believe the problem is that people are replying to all. This sends a copy to the original post author as well as to the list. This was only sent to the list. Did you get two?

Yes,I got two,again,David.So I think it is something wrong with the mailservers.I can't much,about this,but I guess! Maybe could it be some setting,which makes the differens? Maybe could we have a word from the listowner,what he think the problem is!!! Roger
