Many thanks for your help in resolving this problem.

As it turns out I haven't needed to apply your patch (which I wasn't
looking forward to since I installed Postfix the lazy way using apt-get
on Debian).

The machine in question is a 'virtual mini-server', one of several such
things running on the same box. It turns out that the file system set
times according to the host system clock, but the mini-server system
clock was different (and hopefully correct as I was using ntp to sync
it). My service provider has now applied a kernel patch to the system so
that the file time stamps are now based on the mini-server clock rather
than the host system clock.
