    qmail-ldap

    -

    -What is is:
-
- A patch to stock qmail-1.03 to get all user account information
- from an LDAP database. It primary target are POP toaster with
- huge numbers of users (from thousands up to millions).
-
-Some of it's greatest features:
-
- - Users and virtual domains in an LDAP database
- - No local accounts needed
- - Perfect for ISP's to build POP toasters
- - Native mail server clustering
- - Supports size quotas on user maildirs and mbox
- - Automatic creation of home- and maildir's
- - Handles replies with new qmail-reply
- - Extensive logging in qmail-smtpd and qmail-pop3d
- - Supports tarpitting (based on a patch by Chris Johnson)
- - Supports OpenLDAP 1.2.X and Mozilla Directory SDK
- - Includes Antispam-Features (based on a patch by Lindsay Haisley,
-   Rask Lambertsen and Lionel Widdifield)
- - Supports automatic maildir creation when the first mail arrives
- - Support for SHA, MD5, MD4, RIPE-MD160 and clear text passwords
- - Support for NS-MTA-MD5 encrypted passwords used by Netscape Mailserver
-   up to version 2.xx (and later if you simply upgraded).
- - Support for TLS (SSL) encrytion of SMTP mail transport (based on a patch
-   by Frederik Vermeulen)
- - It also supports the password format used by Software.com's
-   Post.Office
- - Fix for qmail-pop3d to make Netscape's mail download status bar
-   working (based on a patch by sven@megabit.net)
- - Fix for oversized DNS packets (based on a patch by Christopher
-   K. Davis)
-
-What's still to do:
- - The big Qmail-LDAP picture
-
-

    - -

    -The qmail-LDAP documentation is here (well, sort of). -

    -This is the fourth 'official' release of qmail-ldap, grab the diff here (release -qmail-ldap-1.03-20000601 and please direct all questions to the qmail-ldap mailing-list qmail-ldap@argus.pipeline.ch. This is my email address.
    -A mailing list for discussion of this patch is available, send mail to qmail-ldap-subscribe@argus.pipeline.ch

    -There are great differences to the previous (19991007) patch.
    -If you still need the previous patch you can get it here -together with even more older stuff.

    -Note: This is NOT point-and-click-and-then-it-works ware!
    -You should have fairly good prior knowledge of qmail and LDAP.     -
