Postfix snapshot 1.1.11-20020718 available

Postfix snapshot 20020718 catches up on a few things that I
implemented before and after the time that I was gone in June.

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.

- The masquerade_domains feature now supports exceptions.  Prepend
  a ! character to a domain name in order to not strip its subdomain
  structure.  More information in conf/sample-rewrite.cf.

- The Postfix virtual delivery agent supports catch-all entries
  (@domain.tld) in lookup tables. These match users that do not
  have a specific [email protected] entry. see VIRTUAL_README and
  man 8 virtual.

For more details, including incompatibilities, see the RELEASE_NOTES
and HISTORY file fragments below.

RELEASE_NOTES fragment:
=======================

	Incompatible changes with Postfix snapshot 1.1.11-20020717
	==========================================================

	The default timeout for establishing an SMTP connection has been
	reduced to 30 seconds, because many systems have an atrociously
	large default timeout value.

	The Postfix SMTP client now logs a warning when the same domain is
	listed in main.cf:mydestination as well as a Postfix-style virtual
	map. Such a mis-configuration may cause mail for users to be rejected
	with "user unknown".

	Postfix no longer strips multiple '.' characters from the end of
	an email address or domain name. Only one '.' is tolerated.

	The SMTP server reject_unknown_{sender,recipient}_domain etc.
	restrictions now also attempt to look up AAAA (IPV6 address) records.

	Major changes with Postfix snapshot 1.1.11-20020717
	===================================================

	The masquerade_domains feature now supports exceptions.  Prepend
	a ! character to a domain name in order to not strip its subdomain
	structure.  More information in conf/sample-rewrite.cf.

	The Postfix virtual delivery agent supports catch-all entries
	(@domain.tld) in lookup tables. These match users that do not
	have a specific [email protected] entry. The virtual delivery agent
	now ignores address extensions ([email protected]) when searching
	its lookup tables, but displays the extensions in Delivered-To:
	message headers.

HISTORY file fragment:
======================

20020705

        Safety: log a warning when a domain is listed in mydestination
        and (virtual_maps or virtual_mailbox_maps).  This configuration
        error causes the Postfix SMTP server to reject recipients
        when the local_recipient_maps feature is enabled.  File:
        smtpd/smtpd_check.c.

200207011

        Portability: in the master daemon, the default now is to
        enable the signal handler code that writes a byte into a
        pipe, instead of the signal handler code that sets a global
        flag and hopes that select() will somehow wake up. File:
        master/master_sig.c. This is needed for some IRIX and
        UnixWare versions, but it should also produce a robust
        result on all other supported systems.

        Performance: the default SMTP connection establishment
        timeout is now 30 seconds, instead of the system default
        which can be atrociously large.

20020712

        When DNS lookup fails while delivering mail, report not
        only the domain name but also the DNS record type.  This
        should clue in people who ask why Postfix can't find a
        domain while nslookup can.  File:  dns/dns_lookup.c.

20020713

        Bugfix: undo change made at 20020610 that causes the trivial
        resolver client to loop when an address consists entirely
        of @ and . characters.  File: trivial-rewrite/resolve.c.

        Cleanup: Postfix no longer strips multiple '.' at the end
        of a domain name. One '.' is silently tolerated. Files:
        trivial-rewrite/rewrite.c, trivial-rewrite/resolve.c,
        global/resolve_local.c. This policy is too distributed.

20020715

        Feature: @domain.tld catch-all map entries for the virtual
        mail delivery agent. Files: global/virtual8_maps_find.c,
        virtual/mailbox.c, smtpd/smtpd_check.c.

        Feature: the virtual mail delivery agent now accepts address
        extensions ([email protected]), ignores them when looking
        up users in its tables, but displays them in Delivered-To:
        message headers.  File: global/virtual8_maps_find.c.

20020716

        Feature: domain names in a masquerade_domains list can now
        be prefixed with !, in order to disable masquerading for
        that domain name and for its subdomains. File:
        cleanup/cleanup_masquerade.c.

20020717

        Bugfix: Mac OS X niscript (Netinfo) update by Gerben Wierda.
        File: auxiliary/MacOSX/niscript.

        Feature: The SMTP server reject_unknown_whatever restrictions
        now also attempt to look up AAAA (IPV6 address) records.
        Jun-ichiro itojun Hagino, IIJ labs. Files: smtpd/smtpd_check.c,
        dns/dns_lookup.c.

20020718

        Bugfix: unnecessary lookups for extended addresses by the
        virtual8_maps_find() routine. Victor Duchovni. His patch
        did not work, nor did my own, but the present version should
        be OK. File: global/virtual8_maps_find.c.
