Description of problem:
Appears to be caused by amavisd. Shows at boot.
SELinux is preventing /usr/bin/perl from 'search' accesses on the directory net.

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

If you believe that perl should be allowed search access on the net directory 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 /usr/sbin/amavi /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
