Newbie installation advice

[nettproffen]

Hi.

Im used to Helm but want to use Plesk on my win2003 servers.

I have 2 win2003 webservers and one win2003 email/stats server.

What is the best practice for email server setup in plesk.
I use smartermail.

I have heard that I need to have a emailserver setup on each webserver. That seems strange. Is it not possible to use PLesk with one emailserver only (one server/IP for email?)

please advice.

Bjørn.
