Configure a local ubuntu server to host multiple sites

Before i start, sorry for any english mistakes. I need someone to configure a ubuntu server to host multiple sites like this: - I already have a configured main site using the server (Apache + Mysql working fine) but still need to get the email working - I need to host another sites in this server using folders inside the www one (apache default), lets call "[login to view URL]" - Those sites must be acessible by they regular URL like "[login to view URL]" and "[login to view URL]" withou use any iframes or anything So i need a fully configured web server AND i must learn at least how to add more sites (have some experience with linux ) The local ports we gona need is working fine now i need someone experienced to do this Waiting for, Thanks in advance
