SELinux is preventing /usr/sbin/clamd from 'open' accesses on the file /var/log/clamd.exim.

*****  Plugin restorecon (99.5 confidence) suggests  *************************

If you want to fix the label. 
/var/log/clamd.exim default label should be clamd_var_log_t.
Then you can run restorecon.
Do
# /sbin/restorecon -v /var/log/clamd.exim

*****  Plugin catchall (1.49 confidence) suggests  ***************************

If you believe that clamd should be allowed open access on the clamd.exim 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 clamd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

This is after reboot and fresh uninstall/reinstall of exim-clamav; default config file with no changes specifies that this is where clamd should log. Running "restorecon" as above fixes it.

Comment 1 Miroslav Grepl 2011-10-10 12:22:47 UTC
/var/log/clamd.exim is mislabled.

# restorecon -R -v /var/log/clamd.exim

should fix it. It looks like you started clamd by hand without using a service script.
