Heads up to Julian sendmail 8.13 (upcoming release) Linux 2.4 Series and broken flock()

[Julian Field]

Hopefully all that is required is
         Lock Type = posix
in MailScanner.conf for these systems.

And I should be able to auto-detect this from the output of
         sendmail -d0.4 -bt < /dev/null
as hopefully it will show up there.
