I set up a Mac mini as both a web server and mail server. $499.
It’s loaded with CMS applications which run on PHP and MySQL (free). Postfix enabler was used to enable and set up Postfix for mail (about 75 accounts)
The site runs Mambo, Expression Engine Core, Joomla, phpBB, WordPress, MediaWiki, Moodle, SugarCRM, MyFAQ.
Sweeet. Simple. Cheap. Works great remotely via Apple Remote Desktop.
