I think you're getting these because I removed the transition from
spamd_t to dcc_client_t, since I thought that with the dcc policy now
being included in the selinux-policy-targeted package, would already be
included.

These all appear to be due to running restorecon in a cron job. Probably
your dcc client building script.
I could add this to the dcc policy (or a separate local module for
restorecon):
cron_system_entry(restorecon_t)
However, I think that the "right" way to fix this would be to use
restorecond and add an entry to /etc/selinux/restorecond.conf (the
manpage for restorecond suggests
/etc/selinux/POLICYTYPE/restorconfiles.conf but that file doesn't seem
to exist, and the restorecond binary includes the string
/etc/selinux/restorecond.conf).
Maybe Dan could comment on that?
