Check out http://www.qmailrocks.org/
It's a step-by-step guide to getting qmail, Clam AV, SpamAssassin, Courier-IMAP and a few bells and whistles running on various OSes (various flavours of Linux, FreeBSD and Solaris), including virtual domains, filtering, mailing lists and webmail (it uses SquirrelMail, but you can skip that and just plonk RoundCube on instead). It's pretty comprehensive - I wish I'd had it to hand when I first started with qmail.
Cheers,
Owen

Hi, I was wondering if any one has a full system working with imap server + smtp server + roundcube (including virtual domains) for examples: dovecout / courier + postfix + roundcube. Thanks.
