I think that my problem with mailspool/logrotate is that it relates to
my mail backup system in which procmail places a copy of every mail (in
mbox format) onto a separate partition on the same machine. This seemed
to cause labelling problems and we went round the houses on this issue a
while back ("Partitions Mounted by fstab" 5 March 2008 -

Thanks for your help - much appreciated...
