MT is NOT a server. Ashish is right that you can use it as a ftp server but the capabilities may be a little low. For a mail and web server than you just CAN'T do it with MT. My advice would be to let MT do the routing and QOS, etc (cause it is really really brave at it) and use a linux distro (any distro) to do the rest.
