I didn't find the reference above but, if you're speaking about the
proposed patch only, I don't think it's the case. The proposed patch
only deduplicate file-identical (up to checksums, that is) messages in
maildirs: a Message-ID collision is not enough to hide a message.
But your comment is very interesting anyhow, as deduplicating on the
basis of Message-ID is indeed something I've discussed with Kevin as
future work. You just provided an extra argument not to enable that by
default.
Cheers.
