Since 2001-09-08 this is precisely what should be happening.  Have you
checked out since then?

If so, could you quote the exact messages from the backend?  Could you
also do a `stat ~/Mail/somennmlgroup/.marks' to see if perhaps there is
something weird with the modtime field? (I guess some network filesystems
could skip that field.  What fs are you using?)
