[Ma-linux] Having problems copying data using cp over nfs

[Przemek Klosowski]

BTW, I use cp -a which is a shortcut for cp -dpR. IT preserves the times
which is useful.

Ah, and try 

tar -C /home/jhart -cf - Maildir | tar -C /mntpoint/email/home/jhart -xf -

which creates an archive on the fly, and is a good idiom to learn
because it uses the filesystem more effectively, especially when you
copy across the network (the latencies on both ends overlap for much
better throughput).
