Webmin alternatives

Everyone knows that Webmin is nasty - it does things in wrong way on a pure and nice Debian (and Ubuntu) systems and for some reason is not included in Debian (post-sarge) or Ubuntu. That does not inspire confidence in a root-running web based software to say the least.
I have a need to have a Linux server and give an administrator the ability to add/remove users, configure some LAMP settings, some email settings (SMTP, POP, IMAP, Spam/Virus protection), Samba and those kinds of everyday system administration tasks on a SOHO Linux server without having to know much about Linux.

Unfortunately I am very hard pressed to find anything that I could just set up and forget. Does anyone have any good experiences on this?
