On closer inspection it appears not to be server related, but Thunderbird related (as you might expect).
Two machines, one having only used Dovecot, and the other only having used Courier *do* indeed show different inbox ordering.
BUT, if I reset the folder and redownload the courier folder then the ordering changes again (and shows this date inconsistency). So it seems that Thunderbird does different things with the same data depending on when/how it was received. Quite possibly it's simply putting in a todays date (when missing) depending on when the headers are first downloaded...?
Sorry for the noise - however, hopefully someone else might see this in the archives if facing a similar question
