Exim will be trying to create a file called <mailbox-name>.lock in the
same directory as the mailbox it is trying to delivery into. There must
be some kind of permissions problem on that directory. It will at the
time be running as the user to whom the message is addressed. Are you
delivering into home directories, or into a general /var/mail directory?
If the latter, you need to have the "sticky bit" turned on in that
directory if you need to have lockfiles working.
