This is indeed the correct behaviour of notmuch. There has been some
discussion on it in the past, I believe with proposals to track both
messages and show only one; but I don't think I've seen proponents of
showing both duplicate messages.

Personally I'd find it rather annoying if I'd see messages twice. But I
do see the value in being sure that your mail gets delivered through the
list. I believe the solution I've seen discussed was for notmuch to
somehow determine which of the duplicates holds the most information
(which would be the one through the list, not the one directly to you).

On the other hand, enough mailing lists destroy this behaviour, see:

spool, around id:87y6lir37f.fsf at vertex.dottedmag
