Postfix snapshot 1.1.9-20020513 will be the last in a while.  It
brings an updated LDAP client module, and ties up some loose ends
from last week.

The difference between a snapshot and an official release is as
follows: the official release does not change except for bugfixes
and portability patches. New features are tried out in snapshot
releases.  Code that works and that stops changing becomes part of
Postfix official version 1.2.

- An updated LDAP client module with new query result filtering,
  and with improved handling of dead LDAP servers.

- A new configuration parameter (resolve_dequoted_address) that
  allows you to choose between technical correctness and safety,
  when resolving addresses of the form user en domain@domain.

    Major changes with Postfix snapshot 1.1.9-20020513
    ==================================================

    Updated LDAP client module with better handling of dead LDAP servers,
    and with configurable filtering of query results.

    In order to allow user en domain@domain addresses from untrusted
    systems, specify "resolve_dequoted_address = no" in main.cf (when
    resolving mail, quote the address localpart as per RFC 822, so that
    @ or % or !  operators in the address localpart remain invisible).
    Although this behavior is technically more correct, it also opens
    opportunities for mail relay attacks when Postfix provides backup
    MX service for Sendmail systems.

Extract from HISTORY file:

20020513

	Bugfix: the LDAP client used the "wrong" @ character in
	addresses with multiple @. LaMont Jones, HP. File:
	util/dict_ldap.c.

	Feature: lots of new LDAP stuff: result_filter (filter to
	expand results from queries), chase_referrals, LaMont Jones,
	HP. The LDAP bind timeout now works thanks to Victor
	Duchovni, Morgan Stanley. File:  util/dict_ldap.c.

	Cleanup: specify "resolve_dequoted_address = no" to prevent
	Postfix from looking inside quotes for extra @ etc. characters
	when resolving an address. This behavior is technically
	more correct, but it opens a mail relay loophole with "user
	@domain"@domain when relaying mail to a Sendmail system.
