[K12OSN] Student email

[Santiago, Nicholas]

Good idea Jim... Here's another to ponder. 

If you set the server up with a dummy domain, for example vassalboro.loc,
the SME server won't route mail to the system's public hostnames. In
essence, their email address is non-routable, as it would be
username at vassalboro.loc.

But this doesn't satisfy David's criteria that the students be able to 
access this from their home. What he is asking for is a "private/local" 
email system that can be accessed by the authorized users (his students) 
from anywhere on the Internet. 

The private/local part is easy - an SME server with a private IP. 
Access from the outside is the hard part. 

What about this: Set up a private SME server as above. Set up an IP 
forward on your firewall that will allow students to get to the private 
server from the outside via WebMail. (Just brainstorming.....) They 
should not be able to mail out since the local server has no public IP 
but the students should be able to get to WebMail from outside.
