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

If you believe that perl should be allowed read access on the online 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 amavisd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

[root@inet18 ~ (master #)]# grep amavisd /var/log/audit/audit.log | audit2allow

#============= amavis_t =============allow amavis_t shell_exec_t:file { read open };
allow amavis_t sysfs_t:file read;
