[xmail] Widespread Use?

[Digitalpeer]

I'm a net admin and CS major in the process of checking out Xmail.  So = far, I really like it, but am curious about how it is being applied out = there.  Where is it being used?  What is the average number of users?  = How much mail in and out a month?  Stability?  Disaster recovery?  How = many servers are running it?  I plan on writing a worthwhile ASP = interface to it if all goes well- is there already a worthy web = interface to it out there? -DiGitalPeeR
