Errr, not true.  The other bugs above went away but this one remained
with MailScanner-4.74.10-1.  I checked the status of /tmp (owner and
group = root, chmod 1777) before running a debug version of 4.74.10-1.
Bang!  It chmoded /tmp to 700 right away, so I changed the permissions 
by hand while the debug version was still churning.  The test otherwise 
finished normally.  I repeated the whole process again to make sure I was
not dreaming.  Same result.

Question:  Does /var/spool/MailScanner/incoming/Locks and locks get
a lot of traffic, or just occasional use when anti-virus profiles are
updated?  In previous versions, all of this lived in /tmp which is
ramdisk in Solaris -- fast.  Will the change to "Lockfile Dir" slow
us down?
