Bugfix: SMTPD proxy didn't send QUIT as the result of code
duplication. Evidence reported by Mark Martinec. File:
smtpd/smtpd.c.
20040311
Bugfix: bad address syntax caused map lookup with zero-length
keys. Problem reported by Andrei Koulik. Files:
util/match_ops.c, src/trivial-rewrite/transport.c.
This package is the snapshot from 20040209.
Postfix aims to be an alternative to the widely-used sendmail
program. Sendmail is responsible for 70% of all e-mail delivered
on the Internet. With an estimated 100 million users, that's an
estimated 10 billion (10^10) messages daily. A stunning number.
Although IBM supported the Postfix development, it abstains from
control over its evolution. The goal is to have Postfix installed
on as many systems as possible. To this end, the software is given
away with no strings attached to it, so that it can evolve with
input from and under control by its users.
allows correct local delivery on multiple hosts while still canonicalizing
visible and sender addresses. (This makes it possible to support vanity
domains and "permanent address" services like iki.fi and pobox.com.)
(mail/postfix should be overwritten)

Portability: master sigchld handler based on writing to a
pipe, so that the master wakes up from select(). Based on
code by Erik Forsberg, Linkoping University, Sweden. File:
master/master_sig.c. Disabled until after the major release.
Code cleanup: Postfix should now run with no alias database.
Code cleanup: local_destination_recipient_limit and
local_destination_concurrency_limit have become first-class
configuration parameters. Files: global/mail_params.h,
*qmgr/qmgr.c, postconf/postconf.c.
20010226
Documentation suggestions by Lars Hecking and Richard
Huxton, Matthias Andree and many others.
Code cleanup: some queue/transport operations need to be
moved, after the code cleanup of the recipient/concurrency
limit handling. Patrik Rak. Files: *qmgr/qmgr_message.c.
--- changes (reverse order)
20010204
Laid the ground work for logging of table accesses. This
will give more insight into how Postfix uses its lookup
tables. User interface comes later. File: util/dict_debug.c.
20010216
Bugfix: the pipe delivery agent expanded $size as if it
were a recipient, instead of expanding it as $nexthop or
as $sender. Reported by Michael Tokarev. File: pipe/pipe.c.
20010221
Bugfix: poor LMTP performance for domains that are listed
in $mydestination, because Postfix would send one recipient
at a time, with multiple deliveries of recipients of the
same message in parallel; a similar problem could exist
with virus scanning and with firewall relay hosts that
forward mail for $mydestination to an inside machine. This
behavior is now changed to depend on the transport-specific
xxx_destination_recipient_limit parameter. This also means
that you can now get qmail behavior for SMTP deliveries by
setting smtp_destination_recipient_limit=1. File:
{qmgr,nqmgr}/qmgr_message.c.
Workaround: Solaris socketpair() can fail with EINTR. Added
a sane_socketpair.c module that joins the ranks of the other
sane_whatever workarounds. Reported by Andrew McNamara.
File: util/sane_socketpair.[hc]
20010222
Documentation: the default main.cf file has a prominent
warning that mynetworks should be properly configured in
order to reject unauthorized mail relay requests from
strangers.
Documentation: the INSTALL document, section "mandatory
configuration file edits" has a section that explains that
mynetworks should be properly configured in order to reject
unauthorized mail relay requests from strangers.
20010223
Documentation: the basic.html document has a section that
explains that mynetworks should be properly configured in
order to reject unauthorized mail relay requests from
strangers.
Feature: new "mynetworks_style" parameter that controls
how mynetworks (trusted networks) is derived from the
inet_interfaces (machine interfaces) setting. Specify
"class" for entire class A, B, C networks; "subnet" for
the local subnets only; or "host" for maximal privacy.
Files: util/inet_addr_local.[hc], global/own_inet_addr.[hc],
global/mynetworks.[hc], postconf/postconf.c.
Portability: MACOSX patches by Gerben Wierda.
Portability: Solaris /dev/null is a symlink, which tripped
up the code to safely open a file before local delivery. We now
grudgingly allow symlinks owned by root. File: util/safe_open.c.
20010224
Bugfix: "postconf mynetworks" ignored the inet_interfaces
setting. That was a very old one. File: postconf/postconf.c.
INCOMPATIBLE CHANGE: POSTFIX NO LONGER RELAYS MAIL FOR
CLIENTS IN THE ENTIRE CLASS A/B/C NETWORK. POSTFIX BY
DEFAULT RELAYS MAIL FOR CLIENTS IN THE LOCAL SUBNETWORK.
Specify "mynetworks_style = class" to get the old behavior.
20010225
Portability: master sigchld handler based on writing to a
pipe, so that the master wakes up from select(). Based on
code by Erik Forsberg, Linkoping University, Sweden. File:
master/master_sig.c. Disabled until after the major release.
Code cleanup: Postfix should now run with no alias database.
Code cleanup: local_destination_recipient_limit and
local_destination_concurrency_limit are not first-class
configuration parameters. Files: global/mail_params.h,
*qmgr/qmgr.c, postconf/postconf.c.
Major changes with snapshot-20010202
====================================
The mailbox file size limits for the local and virtual delivery
agents can be disabled by setting mailbox_size_limit and/or
virtual_mailbox_limit to zero.
Incompatible changes with snapshot-20010128
===========================================
If this release does not work for you, you can go back to a previous
Postfix version without losing your mail, subject to the "incompatible
changes" listed for previous Postfix releases below.
REJECT in header/body_checks is now flagged as policy violation
rather than bounce, for consistency in postmaster notifications.
New mailbox size limit for local delivery (default: 50MBytes). This
limit affects all file write access by the local delivery agent or
by a process run by the local delivery agent. The purpose of this
parameter is to act as a safety for run-away software. It cannot
be a substitute for a file quota management system.
The default RBL (real-time blackhole lists) domain examples have
been updated from *.vix.com to *.mail-abuse.org.
Major changes with snapshot-20010128
====================================
Updated nqmgr (experimental queue manager with clever queueing
strategy) by Patrik Rak. This code is still new. Once it stops
changing (for a long time!) it will become part of the non-beta
release.
Virtual mailbox delivery agent by Andrew McNamara. This delivery
agent can deliver mail for any number of domains. See the file
VIRTUAL_README for detailed examples. This code is still new. Once
it stops changing it will become part of the non-beta release.
Many "valid_hostname" warnings were eliminated. The warnings that
were not eliminated were replaced by something more informative.
SASL support (RFC 2554) for the LMTP delivery agent. This is required
by recent Cyrus implementations when delivering mail over TCP
sockets. The LMTP_README file has been updated but still contains
some obsolete information.
Workarounds for non-standard RFC 2554 (AUTH command) implementations.
Specify "broken_sasl_auth_clients = yes" to enable SMTP server
support for old Microsoft client applications. The Postfix SMTP
client supports non-standard RFC 2554 servers by default.
Major changes with snapshot-20001217
====================================
This release involves little change in functionality and a lot of
small changes to lots of files. The code is put out as a separate
snapshot release so that I have a tested baseline for further work.
All time-related configuration parameters now accept a one-letter
suffix to indicate the time unit (s: second, m: minute, h: hour,
d: day, w: week). The exceptions are the LDAP and MYSQL modules
which are maintained separately.
The mysql client was partially rewritten in order to elimimate some
memory allocation/deallocation problems. The code needs more work,
and needs to be tested in a real production environment.
The local_transport and default_transport configuration parameters
can now be specified in transport:destination notation, just like
the mailbox_transport and fallback_transport parameters. The
:destination part is optional. However, these parameters take only
one destination, unlike relayhost and fallback-relay which take
any number of destinations.
Incompatible changes with snapshot-20001210
===========================================
If this release does not work for you, you can go back to a previous
Postfix version without losing your mail, subject to the "incompatible
changes" listed for previous Postfix releases below.
When delivering to /file/name (as directed in an alias or .forward
file), the local delivery agent now logs a warning when it is unable
to create a /file/name.lock file. Mail is still delivered as before.
The "sun_mailtool_compatibility" feature is going away (a compatibility
mode that turns off kernel locks on mailbox files). It still works,
but a warning is logged. Instead of using "sun_mailtool_compatibility",
specify the mailbox locking strategy as "mailbox_delivery_lock =
dotlock".
The Postfix SMTP client now skips SMTP server replies that do not
start with "CODE SPACE" or with "CODE HYPHEN" and flags them as
protocol errors. Older Postfix SMTP clients silently treated "CODE
TEXT" as "CODE SPACE TEXT", i.e. as a valid SMTP reply.
This snapshot does not yet change default relay settings. That
change alone affects a dozen files, most of which documentation.
This may be an incompatibility with some people's expectations,
but such are my rules - between code freeze and release no major
functionality changes are allowed.
Several interfaces of libutil and libglobal routines have changed.
This may break third-party code written for Postfix. In particular,
the safe_open() routine has changed, the way the preferred locking
method is specified in the sys_defs.h file, as well as all routines
that perform file locking. When compiling third-party code written
for Postfix, the incompatibilities will be detected by the compiler
provided that #include file dependencies are properly maintained.
Major changes with snapshot-20001210
====================================
This snapshot includes bugfixes that were already released as
patches 12 and 13 for the 19991231 "stable" release:
- The queue manager could deadlock for 10 seconds when bouncing
mail under extreme load from one-to-one mass mailings.
- Local delivery performance was substandard, because the per-user
concurrency limit accidentally applied to the entire local
domain.
The mailbox locking style is now fully configurable at runtime.
The new configuration parameter is called "mailbox_delivery_lock".
Depending on the operating system type, mailboxes can be locked
with one or more of "flock", "fcntl" or "dotlock". The command
"postconf -l" shows the available locking styles. The default
mailbox locking style is system dependent. This change affects
all mailbox and all "/file/name" deliveries by the Postfix local
delivery agent.
The new "import_environment" and "export_environment" configuration
parameters now provide explicit control over what environment
variables Postfix will import, and what environment variables
Postfix will pass on to a non-Postfix process. This is better than
hard-coding my debugging environment into public releases.
The "mailbox_transport" and "fallback_transport" parameters now
understand the form "transport:nexthop", with suitable defaults
when either transport or nexthop are omitted, just like in the
Postfix transport map. This allows you to specify for example,
"mailbox_transport = lmtp:unix:/file/name".
The MYSQL client now supports server connections over UNIX-domain
sockets. Code provided by Piotr Klaban. See the file MYSQL_README
for examples of "host" syntax.

Documentation: the canonical, virtual etc. manual pages
did not document the effect of leading whitespace.
20001025
Bugfix: virtual map expansion stopped too early with
self-referential aliases. Reported by Michael Douglass
@ datafoundry.net. File: cleanup/cleanup_map1n.c.
20001026
Horror: postmap and postalias (newaliases) silently lose
the file lock while building a lookup table with Berkeley
DB 2.x and later on Solaris, HP-UX, IRIX, and UNIXWARE.
The result is that table lookups fail while the table is
being built, so that mail is lost. In order to avoid this
misbehavior one has to use an undocumented feature that is
NOT available with the DB1.85 compatibility interface.
Therefore, Postfix now supports three Berkeley DB programming
interfaces of increasing complexity. File: util/dict_db.c.
Bugfix: some character manipulations were not portable for
signed/unsigned characters. Files: global/quote_821_local.c,
global/quote_822_local.c.
Workaround: apparently, some software sends SMTP mail that
begins with "From sender time-stamp". Sendmail silently
ignores such RFC violating garbage, and therefore Postfix
needs to jump another hoop. File: smtpd/smtpd.c.
20001028
Bugfix: the flush server tried to access config files after
going to the chroot jail. Found by Lutz Jaenicke, TU-Cottbus.DE.
File: flush/flush.c.
Update: revised LDAP module from primary maintainer John
Hensley, with contributions from many other people. Files:
util/dict_ldap.c, LDAP_README.
Update: LINUX2 chroot setup script by Matthias Andree,
uni-dortmund.de.
Feature: specify unix:/path/name for LMTP connections over
UNIX-domain sockets, and specify inet:host or inet:host:port
for IPV4. If no unix: or inet: is specified, IPV4 is assumed.
File: lmtp/lmtp_connect.c.
Feature: added UNIX-domain support to the smtpstone test
programs in order to test the LMTP client UNIX-domain
support.
20001030
Bugfix: further testing in preparation for 19991231-pl10
revealed that the DB map code was now broken for every
platform.
20001031
Performance: the slow start (gradually increase number of
parallel connections to the same site) was too gentle and
Postfix would back off too quickly. Files: qmgr/qmgr_queue.c
and nqmgr/qmgr_queue.c.
20001101
FAQ update by Ralph Hildebrandt.
20001104
Portability: RedHat Linux has changed incompatibly, again.
Fixed with the help of Matthias Andree. File: makedefs.
20001109
Cleanup: changed prototype of internal function that did
not return a useful result. File: src/util/vstream_popen.c.
20001110
Workaround: the Debian post install script passes an open
file descriptor into the master server and waits forever.
Reported by Lamont Jones. File: master/master.c.
20001114
Compatibility: added sendmail -G (gateway submission) option
for compatibility with the sendmail rmail command. Requested
by David Gilbert, Velocet Communications.
20001116
Documentation: added MAILER-DAEMON to the list of sample
masquerade_exceptions settings in conf/sample-rewrite.cf.
Suggested by Karl O. Pinc, pop.artic.edu.
Performance: the slow start (gradually increase number of
parallel connections to the same site) was too gentle and
Postfix would back off too quickly. Files: qmgr/qmgr_queue.c
and nqmgr/qmgr_queue.c. Yup, changed the same code, again.
We now allow for a margin above the actual concurrency,
with the size of the initial destination concurrency.
Final solution by Patrik Rak.
Bugfix: the recipient home directory test broke mailbox_transport
support for non-UNIX recipients. File: local/recipient.c.
20001117
Robustness: additional integrity tests for the nqmgr by
Patrik Rak. File: nqmgr/qmgr_message.c.
20001118
Bugfix: the new LDAP client code did not work properly if
the new ldap_domain parameter was not specified. LaMont
Jones, HP. File: util/dict_ldap.c.
Feature: the soft_bounce safety net is extended to the SMTP
server. With "soft_bounce = yes", The SMTP server changes
all 5xx (reject) replies into 4xx (try again) replies.
Documentation: the virtual(5) man page now documents both
Postfix-style virtual domains and Sendmail-style virtual
domains, including their interaction with local usernames,
aliases and mailing lists. Hopefully, this ends some of
the confusion surrounding virtual domain support. Updated
several FAQ entries concerning virtual domain support.
Documentation: added FAQ entry for the biff service.
20001119
Bugfix: per-destination queue names were case sensitive so
that the same site could have multiple queues. Reported
by Patrik Rak. Files: *qmgr/qmgr_message.c.
20001120
Bugfix: per-destination deferred mail logfiles were case
sensitive so that the same site could have multiple deferred
mail logfiles, so that not all mail would be flushed with
ETRN. Reported by Ralph Hildebrandt. Files: flush/flush.c.
Portability: added (int) casts to printf-like arguments
that specify the width of %*letter conversions. On some
systems, sizeof and pointer difference expressions are
wider than an int. Reported by Valentin Nechayev @ lucky.net.
20001121:
Compatibility: Postfix now retries delivery when an external
command is killed by a signal, because people expect such
behavior from Sendmail. File: global/pipe_command.c.
is it in <db_185.h>? no
is it in <db/db.h>? no
is it in <db1/db.h>? yes
and for a good measure they've renamed libdb.a to libdb1.a to make sure
that they break linking, not just compiling.
