Or, after more searching, maybe /etc/pyzor needs to be spamc_home_t instead of spamd_etc_t. A quick chcon -R -t spamc_home_t /etc/pyzor appears to fix my issues, at least temporarily. We should just allow it to read the contents. commit 5e10eee2f0c09a63eb5e85f148edfec28d068621

I recently started doing some maintenance on the pyzor package, which is (most often) called by spamassassin as part of its usual spam checks. The existing policy has a directory set aside for pyzor: /etc/pyzor(/.*)? all files system_u:object_r:spamd_etc_t:s0 but pyzor when called by spamassassin can't access that directory: type=AVC msg=audit(1425604453.271:35249): avc: denied { getattr } for pid=7696 comm="pyzor" path="/etc/pyzor" dev="dm-0" ino=145303 scontext=system_u:system_r:spamc_t:s0 tcontext=system_u:object_r:spamd_etc_t:s0 tclass=dir permissive=0 Took me ages to figure out why pyzor wasn't finding its directory because that denial appears to be dontaudit'ed and I'm not quite sure why. Am I misunderstanding the function of spamd_etc_t? I can see that spamd_t is allowed to look there, and spamassassin does run as spamd_t, but I guess it transitions to spamc_t before it calls pyzor. Also, if this is indeed a policy issue, is there a simple workaround? Thanks.
