Hello to all,
I now have the problem of not being able to recieve messages from yahoo groups list solved.  Several people told me the problem might be with having a spam filter set to high.  Well, that put me on the right track.  I called AT&T tech support.  The first lady told me The problem was with AT&T not allowing certain news groups into the system.  Her suggestion was to go to another news group.  I tried to tell her that I couldn't get people to change there e mail addresses just because AT&T wasn't excepting them.  Then she told me some thing else.  and after I hung up I didn't feel satisfied that she knew what she was doing.  So after a while I called back and got this young lady who took her time and wouldn't give up.  She kept on apologizingfor taking so much time.  I told her that was all right and to take as much time as needed.  I kept on thanking her for helping me.  Finally  after trying every  thing she found a file that was named Mcafee spam.  That was where my messages were.  She renamed the file and for now I took Mcafee off my computer.  I can now send and recieve messages from the list.  so thanks to a young lady who wouldn't give up and  several people on list who gave me the idea of spam the problem is now solved.
thank every one for there help.
