Help: Virtual Hosts and Email

[Maan Jee]

Hi Guys

I am trying to host couple of virtual hosts on my FreeBSD box...

1. How can I make Virtual Hosts, I mean what would be best structure and
strategy?

2. What is the basic procedure in few lines?
3. How can I setup Email Server for example Qpopper? and is it better than
Sendmail or what?

4. How can I setup Virtual Emai for my virtual hosts?

Thanks for your help!
