We have begun to receive the following error for a few of our internal
lists:

An error  occurred while logging  mail to the archives  of the ***  list. An
incomplete copy  of the message  might be present  in the archive  file. The
list is being held to prevent further occurrences of this error. Please take
corrective action and  issue a "FREE ***" command when  you want the message
to be reprocessed.

Serious error occurred - traceback follows
------------------------------------------
>>> Error X'00B0006B' opening file /home/listserv/home/digests.file <<<
 -> Severity: Error
 -> Facility: POSIX/unix error codes
 -> Abstract: Unspecified error (13) - See errno.h
 -> strerror: Permission denied
 -> I/O mode: Record write


When we free the list, we keep on getting the error. I have taken the lists
in question out of logging to the archives to get over the error for the
moment.
Has anyone any ideas what this error means and how i go about fixing it?
