IMAP doesn't understand the concept of crossposting, I think, so this
sounds normal.  How does crosspost mark propagation work for nntp
groups?  I suspect it might be possible to implement something like it
for nnimap by looking in the nnmail message-id split log when applying
marks to a group (i.e., for each article with new marks, look up the
message id in the split log and find out what other groups it was
crossposted to and apply the same mark to it).
