BUT ... you belong to this group, and even this group modifies your
messages. It alters the subject line by adding [Gmail-Users] to it,
and it adds half a dozen lines to the footer. True, no human
moderator manually *wrote* them, and those things never (well, almost
never) change, but they are added nonetheless. Yet Gmail ignores
those changes and sees it as a duplicate and destroys the received
copy.

I subscribe to a ton of Yahoo groups. Most of them automatically add
nearly two dozen lines to the footer, some add more, some add less ...
and they ALL get trashed by Gmail as "duplicates".
Gmail also trashes the ones where the moderator adds either tiny or
large amounts of text to my emails.
If there is a threshold, I haven't seen it yet. Something else may be
going on with the Yahoo group you mentioned, because I do not see that
behavior.
I've developed workarounds. I subscribe twice to many email lists,
using one address for sending emails and another for receiving them.
It's a PITA.
This truly annoying Gmail trait is the longest standing grudge I have
with Gmail. I cannot understand why they can't just make it a user
option, whether to trash duplicates or let me keep them. It should be
MY choice, not dictated by their arrogance. They are not doing me any
favors by trashing those messages. It does not "save me time and
prevent clutter".
