I continue to read the .seen files as I am learning that this mecanism was still present in 2.3.x

Far out.  Bloody reconstruct.  Don't do that.  Copy /var/lib/imap

Probably because you're missing other stuff :(

It should just find the seen data during the upgrade.  I'd
be interesting in knowing how it didn't... can you send me
an example .seen file from someone who doesn't mind it?
