Log file of the problem:

Error: Package: amavisd-new-2.8.0-8.el6.noarch (epel)

           Available: clamd-0.98.1-1.el6.x86_64 (epel)

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

Is there a way to disable amavisd-new until that it'll work with Cent OS?

thanks!
