I'll try setting that variable, since all I'm trying to do is use gnus
to move my old mail from existing nnmh mailboxes into IMAP, preserving
the ticked flag.

(I did used to use MH-E, and I used procmail to deliver into nnmh - I
don't use gnus for splitting, wanting my mail presplit, especially now
that I use IMAP and other clients (including a Palm TX) to look at
INBOX.

Thanks very much for the hint.
