Well, technically the duplicate is usually created by the sender's
mail server when one sends a mail to two different addresses.  The MUA
only creates one mail with one ID.

This debate will never end and is therefore pointless.  I doubt you
will convince many people to switch to a different MUA just to spare
you from duplicates.  Some people don't even have the choice.  Has
nobody come up with a plugin for MS Outlook, yet, that implements
proper list handling?

I guess the first to arrive wins.  Unfortunately, this is usually the
direct mail.  This is annoying when one uses list headers to sort
