} 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.

The other alternative is to make the *directory* group writable, set the
group to something appropriate (like mail - normally *not* the exim
group), and have a group = mail in the appendfile transport. The MUA
programs would then typically be setgid mail. This is the Sys V approach
which I tend to prefer personally (the sticky directory tends to be used
by BSD systems).

This stuff used to be in one of the usenet FAQs - anyone got a reference
to it?
