Eu encontrei a resposta:
Observe que este sistema é o Fedora 20.
O SELinux estava negando o clamscan de escrever, criar e mais para o sistema.
Siga as instruções no solucionador de problemas do SELinux para permitir clamscan o acesso e repita para todos os acessos. Houve também uma negação no mailx mas que não fez nada visível para o processo, funciona!
Aqui estão duas das negações do SELinux:
SELinux is preventing /usr/bin/mailx from ioctl access on the file .
***** Plugin catchall (100. confidence) suggests **************************
If you believe that mailx should be allowed ioctl access on the 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 mail /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
