you need i.e combination of postfix amavis clamav spamassassin dovecot
and perhaps some database or directory service like ldap or mysql
in a ha setup with shared storage ( drbd/nfs etc ), some webmail like
horde and/or an admin gui like postfixadmin running php apache webserver
thats a lot of work , if your newbie try testing on some vm setup first
for getting an idea what to do i.e look at
dependig to your recent setup you might consider cloning config files
sorry there is no easy and short answer to your question
