Sorry if the subject is a bit vague.  I wasn't sure how to summarize this.

I am building a new server (CentOS4.2) and I am trying to stay with RPM
installs as much as possible.  The problem is with packages that I would
like to keep more up to date than allowed by the repositories.  This will be
a mailserver doing spam and virus checking.  As such, I want SpamAssassin
and ClamAV to be as up-to-date as possible.  The current rpm for ClamAV is 6
months and 3 releases behind.

What is the best way to keep these packages up to date while avoiding
dependency issues in yum?
