[Postfix espanol] Postfix snapshot 20011210

[Wietse Venema]

Postfix snapshot 20011210 catches up on recent developments, but
there still is a lot of contributed code in the backlog that needs
to be processed.

The stable non-Beta Postfix release (20010228) does not change
except for bugfixes and for portability fixes. New features are
tested out in snapshot releases.

See the RELEASE_NOTES below for a description of incompatible
changes and new features.  See the HISTORY file below for a summary
of all changes.

The source code will appear soon on the download sites listed
on http://www.postfix.org.

Primary site:

	Incompatible changes with snapshot-20011210
	===========================================

	Postfix SMTPD access maps no longer match non-local mail addresses
	that contain multiple domains (user en dom1@dom2, user%dom1 en dom2,
	etcetera).  This change prevents false or spurious matches.
	Non-local multi-domain addresses are already prohibited from matching
	permit_mx_backup and the relay_domains-based restrictions.

	Stricter checking of Postfix chroot configurations.  The Postfix
	startup procedure now warns if "system" directories (etc, bin, lib,
	usr) under the Postfix top-level queue directory are not owned by
	the super-user (usually the result of well-intended, but misguided,
	applications of "chroot -R postfix /var/spool/postfix).

	The Postfix sendmail command no longer exits with status 1 when
	mail submission fails, but instead returns a sendmail-compatible
	status code as defined in /usr/include/sysexits.h.

	Major changes with snapshot-20011210
	====================================

	Updated LDAP client module by LaMont Jones, with control over
	verbose logging of LDAP library routines.

	More usable virtual delivery agent, thanks to a new "static" map
	type by Jeff Miller that always returns its map name as the lookup
	result. This eliminates the need for per-recipient user ID and
	group ID tables.  See the VIRTUAL_README file for more details.

	Much-needed documentation on how to configure header/body filters:
	sample regexp and pcre lookup tables for header/body filtering,
	and updated examples in the regexp_table(5) and pcre_table(5) manual
	pages.

	Configurable PIX firewall <CR><LF>.<CR><LF> bug workaround behavior:
	the workaround is turned off when mail is queued for less than
	$smtp_pix_workaround_threshold_time seconds (default:  500 seconds)
	so that the workaround is normally enabled only for deferred mail.
	The delay before sending .<CR><LF> is now controlled by the
	$smtp_pix_workaround_delay_time setting (default: 10 seconds).

20011128

        Robustness: add a file size limit to the sendmail and
        postdrop submission programs to stop run-away process
        accidents. This is not a defense against DOS attack.
        Files: sendmail/sendmail.c, postdrop/postdrop.c.

        That resulted in a considerable amount of work to properly
        propagate "file too large" conditions back to the sendmail
        mail posting user interface. Took the opportunity to express
        other mail submission fatal exits with the <sysexits.h>
        exit status codes.  Files: sendmail/sendmail.c,
        postdrop/postdrop.c.

20011129

        Maintenance: dict_ldap.c wasn't updated after the revision
        of the string matching routines. File: util/dict_ldap.c.

20011208

        Maintenance: LDAP module and documentation from LaMont
        Jones.  This version adds verbose logging for LDAP library
        routines. Files: src/util/dict_ldap.[hc], LDAP_README,
        conf/sample-ldap.cf

        Portability: made memory alignment restrictions configurable.
        File: util/mymalloc.c.

        Bugfix? Avoid surprises with source routed destinations
        and OK entries in SMTPD access maps. File: smtpd/smtpd_access.c.

        Security: "postfix check" looks for damage by well-intended
        but misguided use of "chown -R postfix /var/spool/postfix".
        That would make chrooted Postfix less secure than non-chrooted
        Postfix.  These extra tests may cause complaints with
        third-party patches such as TLS that introduce their own
        files into the jail.

        Feature: static map type that always returns the map name
        as lookup value, regardless of lookup key value. Contributed
        by Jeff Miller (jeffm at ghostgun.com).

        Feature: turn off the PIX <CR><LF>.<CR><LF> workaround for
        the first mail delivery attempt, i.e. when mail is queued
        for less than $smtp_pix_workaround_threshold_time (default:
        500) seconds. New parameter $smtp_pix_workaround_delay_time
        to control the delay before sending .<CR><LF> (default: 10
        seconds) when doing the PIX <CR><LF>.<CR><LF> workaround.
