I'm looking for the Red Hat equivalent of this Debian statement

"apt-get –y install postfix mailscanner spamassassin bind9 clamav ssh
webmin webmin-core logwatch libspf2-0 libmail-spf-query-perl"

"yum search" can't find some of the packages. Is there some sort of
online DB or something that I can search through to see which
repository I need to enable for some of those programs?
