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