There are some more contribs, I wish to add to the SME 6.01 plus script:
rpm -ivh joe*.rpm (Texteditor with Wordstar-like commands)
rpm -Uvh e-smith-advworkgroup*.rpm (many Advanced workgroup settings for Samba, to turn off oplock support and many more)
rpm -ivh e-smith-phpsysinfo*.rpm (last available RPM for phpsysinfo, though newer version of phpsysinfo exist)
echo SME Server 6.0.1-01 >/etc/redhat-release (to get rid of "N/A" in Distro Name. This is fixed in the newest phpsysinfo version)
rpm -ivh e-smith-power*.rpm (Power Management for SME, so that you can shutdown the SME Server with the power button (may require additional BIOS settings))
rpm -ivh smeserver-qmHandle*.rpm (displays different mail queues in the web panel "Qmail Queue management")
