At least "answered" would be nice, from that reason I currently tend to
the proceeding via Message-ID lines.

Thanks for this clearification! After comparing some cyrus.header files
from different folders and "my" seen file, I think I understood ;-)
While copying the mailbox the message UIDs change, at least as far as I
can see. So, one might be able to replace the mailbox IDs in the seen
file be the mailbox IDs of the copied version, but the message UIDs
referenced to are out-dated. Or do I miss something?

Well, actually only the files/message themselves are touched. Ok,
they're not simply touched but deleted ;-)
Further Cyrus files (cyrus.*, seen state, subscription list)
are not affected. Furthermore one might assume that they correspond to
the mailbox contents after deleting any "wrong" files/messages.
I hope to find a reasonable approach to create a list of unnecessary
Message-IDs and their corresponding files, which might be piped to
remove. Keep you informed.
kind regards, thanks again,
Thorsten
