My procmail mailing list does not require any modification to XWiki. It
uses the existing capability of the mail plug-in to display messages
from an IMAP store. When messages arrive, I chose to access the database
directly using JDBC rather than invoke something like "wget
http://www.mywiki.com/..." for performance and reliability. I have seen
other people are interested in how to access the database from outside
of XWiki, so maybe this would be a useful example.
The command line java program is invoked with this shell script:
#!/bin/sh
java -cp
/usr/local/tomcat/common/lib/mysql-connector-java-3.1.7-bin.jar:. \
XWikiMail $1 $2 $3 $4

Class.forName ("com.mysql.jdbc.Driver");
Connection con = DriverManager.getConnection(url, dbuser, dbpwd);
Statement stmt = con.createStatement ();
ResultSet rs = stmt.executeQuery (query);
while ( rs.next() ) {
String member = rs.getString(1);
String query2 =
"select xws_value from xwikiobjects join xwikistrings on xwo_id

xwo_classname='XWiki.XWikiUsers' and"

stmt.close();
con.close();
}
}
Here's a procmail rule that distributes mail sent to the mailing list
<group>(a)<wiki>.xwiki.com (I've simplified my original script for clarity).
:0
* ^(To|Cc):.*\/[a-z]+@[a-z]+\.xwiki\.com
{
GROUP=`echo $MATCH | sed s/@.*//`
SITE=`echo $MATCH | perl -pe "s/.*(a)([^\.]*).*/\1/;"`
XWIKISENDMAIL=`xwikimail $SITE $GROUP`
:0 c
$SITE.$GROUP # Store messages in folder like
mywiki.mygroup
:0
! $XWIKISENDMAIL
}

Hi,
Nice, can you send us also a diff with your modification on the mail
plugin. Can we integrate them in Xwiki?

I have integrated a mailing list with XWiki. The
mailing list is built
with procmail, which invokes a command line Java program to extract the
email addresses from the XWiki database and forward each message. All
the emails are archived in a IMAP folder which is viewed by this
template code:
<h3 class="heading-1">Mail Archive</h3>
#set($user = "xxx")
#set($pass = "xxx")
#set($fldr = "${context.database}.listname")
#set($store = $xwiki.mail.getStore("imap"))
$store.connect("localhost", $user, $pass)
#set($fldr = $store.getFolder($fldr))
$fldr.open(1)
#set($msgnum = $parameterParser.getInt("msg",0))
#if($msgnum != 0)
<a href="?">Message Index</a>
\\
#set($mail = $fldr.getMessage($msgnum))
From:
#foreach($from in $mail.getHeader("from"))
$xwiki.getFormEncoded($from) #end
\\
To:
#foreach($from in $mail.getHeader("to")) $xwiki.getFormEncoded($from)
#end
\\
Subject: $xwiki.getFormEncoded($mail.subject) \\
Message:
#if($mail.isMimeType("text/plain") || $mail.isMimeType("text/html"))
$mail.getContent()
#else
(Unable to display)
#end
#else
The following mail was sent to the list
during the past year:
#set($count = $fldr.messageCount)
Showing $count of $count messages:
<table class="wiki-table" cellpadding="0"
cellspacing="0" border="0">
<tr class="table-odd">
<th>Subject</th><th>From</th><th>Date</th>
</tr>
#foreach ($i in [$fldr.messageCount..1])
#set($mail = $fldr.getMessage($i))
<tr>
<td>
<a
href="?msg=$mail.getMessageNumber()">$xwiki.getFormEncoded($mail.subject)</a>
</td><td>
#set($froms = $mail.getHeader("from"))
#foreach($from in $froms) $xwiki.getFormEncoded($from) #end
</td><td>
#if($!mail.sentDate)
$formatter.formatShortDateTime($!mail.sentDate)
#end
</td>
</tr>
#end
</table>
#end
$store.close()
