Sure, Rick and Bilal as volunteered. 
I will take care of the POP3 protocol provider implementation.
(more specifically javax.mail.Store and javax.mail.Folder
implementations and support classes for POP3)

Since Rick has already done work on the Message classes maybe he can
help with the protocol specific Message Classes. Can you ???
I was thinking of doing the SMTP authentication first, since most of my experience with the javamail apis have been in the context of debugging some SMTP problems. I'm familiar with the output transports, but not looked at any of the input stuff yet.
Note that outputing the message format is handled by JAF Handlers for each of the MIME types. The support for decoding the message content may already be in there. . 
I think Bruce is looking into IMAP, but he maybe busy with other things.
So Bilal can you dig into IMAP stuff after checking with Bruce.

And there is also the testing part. Any volunteers to test it and
possibly expand on the unit tests??

Also Bruce did mention that, the intention is to move the JavaMail
implementation to a sub project in the future. So maybe it's a good idea
to make it Geronimo independent.
Anyways a separation of concerns is always a plus point.

I think we should wait until 1.1 to ship this. Even if we got it implemented this week, I don't think we will have time for any serious testing.
As for the timeline and breakdown detailed below, it looks great. Can you coordinate with the other volunteers? 

Thank you for stepping up to the plate on this; I really appreciate it.

Bruce/ Dain,

Can u guys please comment on this?
(below is the break down from my reading/research)
I would like to know if this is going in release 1.0 or 1.x ?? (somebody 
else asked this question too)

Since there is a smtp transport already written I believe there is at
least a minimum implementation of the Message class.

If so we can sub class it and provide POP3 or IMAP Message classes.
However how work has been done on it mile MultiPart and MimePart etc..?

Is anybody willing to tackle the Message (which conforms to
specifications RFC822 and RFC2045) then I can concentrate on POP3 and
Bruce on IMAP.

Since this Message is a beast on it's own it maybe too much for one
person if the timeline is too short.

At least if somebody can analyze and then summarize (reading the whole
thing will kill you :) ) it, then I can code the Message thingy.

Any volunteers ???

Ok here is what I have right now for POP3.

I have gone through the RFC 1939 in detail and here is the summary. I
have also gone through the JavaMail API spec. Started a bit if coding.
I can come with a basic POP3 implementation that connects, authenticates 
and list/retrieve/delete messages by Tuesday the earliest.

Next on my list is message processing according to RFC 822.

After that I will look into authentication.

Is this timeline OK????

POP3 protocol stack
=====================
I will start ASAP on the connection management and the mandatory POP3
commands.
           USER name               valid in the AUTHORIZATION state
        PASS string
        QUIT

        STAT                    valid in the TRANSACTION state
        LIST [msg]
        RETR msg
        DELE msg
        NOOP
        RSET
        QUIT


Authentication
===============
For now I will only work on USER/PASS, but some servers do not support
plain text authentication.
However I need to find out more details about the AUTH(RFC 1734) command which use encryption. Same thing is used for IMAP. (didn't have time to 
investigate).

Message Format (RFC 822)
=======================
A whole new beast to be conquered. Again I didn't have time to go
through in detail. Will give an update by Monday evening if possible.

Guys, is this too much time??? What is the deadline??? do we need this
before ApacheCon ??

Regards,
Rajith.

I guess we can later move it to it's own sub-project so other Apache
users can use it as a standalone library. Just so that they don't go
through the same trouble we are experiencing.

Yes, absolutely. The goal is to offer implementations of transports
for IMAP, POP3, SMTP and maybe even Mbox and Maildir eventually.
