Subject Re: Summer of Code - JAMES Fastfail and Clustering
Date Fri, 03 Jun 2005 08:18:44 GMT
I suggest you subscribe to server-dev@james.apache.org
and get involved in the discussions there.

I don't know anything about the clustering proposal.
I think the google summer of code is intended to be a three month
"engagement" and I suspect that three months full-time is more than
plenty time to accomplish either of these two goals.

In my opinion (There may be some disagreement about where we're going
with this!) Fast Fail is about extending the SMTP protocol to include
validations which allow the server to terminate the conversation
before it wastes valuable resources downloading undeliverable, spam or
malicious email, or mail which violates some kind of other policy
(maximum size, user mailbox size that kind of thing).

The James project want to implement this is a way which complies with
our architectural policy.

Although the policy isn't written down it is clear from looking at
James' code that this change will have to be implemented such that the
protocol handlers are re-desinged in a modular way, and in a manner
sugested by an OO analysis of the general process of handling
protocols of this class. (ascii stateful request/response over tcp/ip)
There are one or two options here, and one part of the task is to try
to merge everyones requirements and arrive at an approach which gains
the consensus of the group. The next part is to design some kind of
simple API (and implement it in James) which will allow "rules" to be
developed and applied declaratively through configuration, in keeping
with the way the rest of James functionality is defined. This will
involve identifying the set of data which the server should make
available to the rules.
The third and final part is to then implement some of the required
rules and release it for testing by the community.
