First commit to James Mailbox over HBase

Today I made my first commit to the HBase mailbox implementation for James, the GSoC project I'm working on. It's not much, I just added a simple implementation for MailboxManager and Mailbox interfaces but it feels good. It's what I was preparing for the past couple of weeks.

The above interfaces are used to access mailboxes from the mailbox store. The mailbox is modeled as described in SMTP RFC and Internet Message Format RFC.

In short, a mailbox can be used to refer either:
  • a character string that represents an email address
  • a store; a place used to deposit a user's emails

Not all emails hava an associated store, for example email aliases do not.

A more detailed explanation can be found on wikipedia.

For best results check out the latest RFC documents.

The project is hosted at http://code.google.com/a/apache-extras.org/p/mailbox-hdfs/. The sources are managed using mercurial and you can build them using Apache Maven.
