And another vote …

I find this a particular problem because I’m on a club committee where 
we have a committee@… address that expands at the server to all of us. 
The first reply-all goes to the originator as themselves, plus 
committee@… which includes the originator. Something seems to limit 
this to three copies of every email, but someone’s reply can be from 
any of the three. If I delete the ‘wrong’ duplicate I get a gap in 
the thread. (Add to this the fact that I have two function based entries 
in the committee@… expansion, collected from two different IMAP logins 
on the same server, and I soon get confused).
