Ok,
When i get time i will write this up for ppl, but for now:
I am using a file store, with the exception of users - these are in a jdbc
store (mysql).
Configure james as per normal, but add the JDBCVirtualUserTable maillet:
<mailet match="All" class="JDBCVirtualUserTable">
<table>db://maildb/VirtualUserTable</table>
</mailet>
At the moment i havnt completed the code for dealing with domains, so you
have to add to the servername section each domain you want to host.
To add users, i am not usign the admin tool (i am doing it directly in the
database). I am also starting to write a web based tool to manage
addresses.
Addresses reuqire two entries - one in users, and one in virtualusers.
In the virtualusertable for my address ([EMAIL PROTECTED]) you have:
user: d.perry
domain: netcase.co.uk
target_address: d.perry..at..netcase.co.uk
In the users table for my address you have:
user: d.perry..at..netcase.co.uk
pwdHash: (sha encrypted junk)
pwdAlgorithm: SHA
useForwarding:0
forwardDestination:(NULL)
useAlias:0
alias:(zero length string)
Basically you have this pair for every user.
Also can add forwarders to virtual users. (including % in user)
Now down to the customisations:
The modified source, james.jar, and complete james.sar are available at:
http://www.netcase.co.uk/daniel/james/
This whole system relies on accounts being stored internally using ..at..
instead of @ otherwise the maillet tries to route it, and gets annoyed.
But, people are logging into smtp, and pop3 using @ symbols, so i've bodged
the java files to make this work - on the appropriate commands it replaces @
with ..at..
This still relies on you setting the account up either manually, or through
the admin tool as ..at..
As i said, i am planning on finishing the code so that it automatically
treats any domains in the virtualusertable as local. This will get rid of
any changes required in config.xml on a per domain basis.
I am also planning on writing a simple web app for administering the email
addresses.
Note that i found all this much easier to understand and setup, that i did
getting any of sendmail/qmail/etc to work at all.
Daniel.

What you are doing looks like it will work for me. But could you give
me more details? I assume you now set up mailboxes in the admin tool
using:
adduser [EMAIL PROTECTED] password
right?
This means that now you have add/modify a mailet to know to send it a
box by this name rather than a box named "user". How do you do that?
What kind of patch did you have to make to James as you referred to?
Finally, does this work with file store as well as database store?
Thanks.
Jerry

This is true, pop3/smtp dont have a hostname header - but they do have a
to
address and a login - so you can work it out.
Incoming mails have a hostname in the to address.... (unless you're
accepting mails to an ip.... which i think you have to do without).
Logging into server - use [EMAIL PROTECTED] as the username.
This works effectively for me. (note you have to patch james's code to
work
around not beign able to have @s in usernames)
With very little effort james does provide a good virtual hosting
solution.
Btw, i have been working with a modified version of latest stable james.
I
havnt checked out the cvs verion of james - what new virtual hosting
features will be added? Will i still have to patch it to convert "@'s"
to
"..at.." and also add code for treating any domains in virtual host
table as
local?
Daniel.

to
me to be a pretty basic function and should be > native such as
with
Apache and Tomcat.
Yes I'm going to do it, I've already done it once, and lost it in
an
hdd crash :-(
I'm waiting until Noel's merged our two main branches, and will
probably be implementing JNDI for resource lookups first.
You should be aware that IP based Vhosting *is* fairly
straightforward, but name based vhosting isn't as there is no
equivalent in POP or IMAP to http's "Hostname" header for telling
us
what name you're trying to get.
