It will be a library call and it would require more debugging. Basically
I would also try to run it in permissive mode

# semanage permissive -a spamc_t

to see if you can get more AVCs.


Thanks for the reply. I did as you directed and got a new AVC in addition to the one I identified previously:

SELinux is preventing pyzor from open access on the file /var/lib/rpm/Packages.

*****  Plugin catchall (100. confidence) suggests **************************

If you believe that pyzor should be allowed open access on the Packages file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep pyzor /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
