This domain was added to just define a context and interfaces for
mailscanner_spool_t so other domains could use it. I have never used
mailscanner and have no idea how to set this up.  I guess we could label
/var/spool/MailScanner with a clamscan_spool_t and add the interfaces to
there.  The only domain that uses mailscan_spool is

	mailscanner_read_spool(procmail_t)
	mailscanner_manage_spool(clamscan_t)
