If people use reply-to-all they can definitely delete the
CC-to/Send-to-author line.

Sorry, I was to write "quite a lot _people_ are able not to send
duplicates."

Don't know? That's the coders problem. If he doesn't want to hack that
he should instead implement a good ML-handling. :)

If this is so, the MUA, as you said, should be able to
recognise and merge/delete duplicates - also before they are send. I
doubt the ID is given when the mail has reached the first server.

But what I maybe did not express well enough was: how can the MUA
decide if the CC-to/Send-to duplicate should be removed or the
duplicate from ML? Sometimes there are even triplikates (can one call
that so?) sent...
