Yep, very interested. So, "serving IMAP from Maildirs" - from the filesystems perspective, can you describe that in detail for me? I would guess that means a shallow directory tree, with quite large directories (how large?) and many (how many?) small files? (how small on average?) How frequently are files added/removed?
Is this easily reproducible for you? If so, can you send me enough details that I can try to reproduce it locally?
thanks.
