I just took a look at the /var/spool/listserv directory and was
surprised to see thousands of error files, most of which are months old.
2 questions:
a) what are these (file names are:
number-x-supd.job.error
listname-maildist.error (lists which do not run on my server)
some-odd-number.error
b) is it safe to delete them?
