-<h1>Email Forwarding</h1>
-<p>
-Emails to @debian.org addresses now go through a LDAP distributed email system.
-This system uses the forwarding field in the LDAP directory to route mail
-without passing it through a users .forward file on a single host.
-Multiple machines participate in the forwarding to provide redudancy.
-<p>
-Each forwarders inspects the LDAP database
-to see if foo@debian.org has forwarding set to an address, if so the <i>envelope
-to address</i> is rewritten and the message redirected to the new address.
-Otherwise the message is relayed to master.debian.org for processing by the
-users .forward files. If email forwarding is setup then .forward files are
-<b>NOT</b> considered. Extension addresses (foo-lists) are always routed
-directly to master for processing.
-<p>
-All machines also use the forwarding attribute as a default destination for
-email. If the user has a home directory and no .forward file the mail is
-forwarded rather than delivered to /var/spool/mail. This makes sure cron
-reports, bug responses and other unexpected emails are not misplaced.
-<p>
-If you set the forwarding address to be a specific Debian machine and do
-not create a forward file then that machine will spool the mail to
-/var/spool/mail instead of creating a mail loop.
-<p>
-The email forwarding can be easially reconfigured using GnuPG:
-<pre>
-echo "emailforward: foo@bar.com" | gpg --clearsign | mail change@db.debian.org
-</pre>
-or by visiting <a href="https://db.debian.org/login.html">db.debian.org</a>
-<p>
-You can test the email routing by using the command <tt>/usr/sbin/exim -bt
-foo@debian.org</tt>
-<h2>procmail</h2>
-If you use procmail for your main mailbox, PLEASE, erase your .forward
-file and put a .procmailrc in its place instead. This feature has been
-supported on debian.org machines for a good while now, and will continue to be
-supported.
-<p>
-The correct way to invoke procmail for extension addresses is "|/usr/bin/procmail [options]"
-Ignore the IFS=".." stuff in the procmail man page.
-<h2>MailBox formats</h2>
-Email can be saved to mailboxes or maildirs by using the correct lines in a
-.forward file:
-<p>
-Mailbox format files "/debian/home/foo/Mbox"
-<br>Maildir format files "/debian/home/foo/MDir/"
-<p>
-To deliver to /var/spool/mail/foo use a construct like '|/usr/bin/procmail
--m /dev/null'. Putting the mailbox path will not work. You must use
-absolute paths for mailboxes, qmail-like ./ paths are not supported by
-Exim.
-<p>
-Also, 'Exim Filter' files are deliberately turned off.
-<h2>Delivery Environment</h2>
-Some environment variables are set per-message (not quoted! Careful!)
-It is important to note that the environment variables dealing with
-addressing apply to the ENVELOPE address are are totally completely
-unrelated to the actual contents of the message:
-<p>
-'Standard' Env Variables:
-<ol>
-<li>EXTENSION (the 'foo' in .forward-foo)
-<li>LOGNAME,USER (your user name)
-<li>SENDER (envelope originator of message)
-</ol>
-<p>
-'Qmail' Env Variables:
-<ol>
-<li>EXT == EXTENSION
-<li>LOCAL = (the entire bit before the @)
-<li>RECIPIENT = (the entire envelope to)
-</ol>
-<p>
-Such that, <i>$RECIPIENT = $LOCAL-$EXTENSION@<something></i>.
