Production Deployment

[N Kapshoo]

I want to evaluate James as an integrated mail solution for a very large web
application.

I have successfully deployed on my local box and used JavaMail to test basic
email.

What I am unclear about is -
How are production deployments of James typically done? I would be looking
to support a very large volume of email and would also be writing a webmail
solution that sits with the rest of our application.
Is James typically deployed inside a servlet container for production? How
do I go about writing mailets and deploying them?

Lastly, if I want to create/delete users programmatically, how would my java
code in the container make james server api calls?

Thanks in advance.
