Can I get any performance benchmarks, besides those from the wiki?
How does it compare to legacy, well established MTA like postfix,
sendmail, qmail, etc. in terms of performance and/or features?


See http://james.apache.org/server/3/feature-perfomance.html with tests made on V3 snapshot from a few months ago.

How usable is the IMAP support? I saw some older posts and recent JIRA
issues that stated IMAP is not fully supported. I will read more on
the documentation page, please notify me if the pages need to be
updated.


RFC3501 (IMAP4 rev1) is fully supported.
You can read on [1] about additional extensions support.
The JIRA you refer to are certainly about supporting additional extensions, such as the one mentioned on [2].

Yeah RFC3501 is fully supported. We also support many other extensions. At the moment we have the following extensions supported in imap-trunk:

IMAP4rev1 LITERAL+ CHILDREN I18NLEVEL=1 WITHIN ESEARCH SEARCHRES IDLE NAMESPACE UIDPLUS UNSELECT AUTH=PLAIN SASL-IR ENABLE

I guess the next extensions I will working on are SORT,ESORT,CONDSTORE and QRESYNC


We believe standard IMAP is pretty good (see [3]). In house, we have the integration tests ([4]) that simulates the IMAP functionalities.
We also need to run other tests such as [5] (still to be done).

[1] http://svn.apache.org/repos/asf/james/imap/trunk/src/site/xdoc/index.xml
[2] http://www.iana.org/assignments/imap4-capabilities
[3] http://wiki.apache.org/james/Server3ClientCompatibility
[4] http://svn.apache.org/repos/asf/james/mailbox-integration-tester/trunk/
[5] http://imapwiki.org/ImapTest

I ran [5] in the meantime and we pass every test except of two which are a bit exotic and not quite correct if you ask me ;) But thats for an other mail...


Weak points:
- 3.0 not yet used widely, so may still contain issues.

I know from at least one company which is already using 3.0-SNAPSHOT in production and it works quite well for them....

Agreed, I will mention this and I hope to get more input from the
audience. Some of them are sys-admins and have some experience with
mail servers.


Do you plan to post your presentations on slideshare?
Would this be the case, we will push your link on @ApacheJames twitter (let's start buzzing :)

That would be great!


Good luck for james at RLUG meetings (just read that on http://ieugen.blogspot.com/

We will look to aggregate your blog on planetapache.

Btw, on my side, my "summer break" will begin a bit later (my client is
asking for me...). As discussed, I will commit a few hadoop/hbase samples in
my git tomorrow (my new macs will help me for :)

Great, I look forward to that.


It will be a "work in progress".


Cheers,
Norman
