Cleanup: removed spurious warning when the cleanup server
attempts to bounce mail with soft_bounce=yes. Problem
reported by Ralf Hildebrandt. File: cleanup/cleanup_bounce.c.
Bugfix: null pointer bug when receiving a non-protocol
response on a cached SMTP/LMTP connection. Report by Brian
Kantor. Fix by Victor Duchovni. File: smtp/smtp_reuse.c.
in post-extract.
I exchanges few mails with Wietse and he refused to fix the "==" lines and
instructed me to simply remove the offending file. Instead of having a patch
for a file which is not used by pkgsrc I think it makes sense to remove it.
20060217
Bugfix: don't terminate with a non-standard exit status
when the pipe-to-command feature has a problem before it
executes the command. File: global/pipe_command.c.
20060223
Bugfix: detect integer overflow when multiplying time values
with non-trivial time units. File: global/conv_time.c.
20060307
Bugfix: reset the msg_cleanup() fatal error handler in child
processes. See also change 20060217. Files: postlock/postlock.c,
master/multi_server.c, global/mail_run.c, util/vstream_popen.c.
Postfix now preserves uppercase information while mapping addresses
with canonical, virtual, relocated or generic maps; this happens
even with $number substitutions in regular expression maps. However,
the local(8) and virtual(8) delivery agents still fold addresses
to lower case.
By default, Postfix now folds the search string to lowercase only
with tables that have fixed-case lookup fields such as btree:,
hash:, dbm:, ldap:, or *sql:. The search string is no longer case
folded with tables whose lookup fields can match both upper or lower
case, such as regexp:, pcre:, or cidr:.
For safety reasons, Postfix no longer allows $number substitution
in regexp: or pcre: transport tables or per-sender relayhost tables.
Postfix snapshot 20051220 provides a plug-in architecture for SASL
authentication. With this, Postfix can support multiple SASL
implementations without source code patches.
Incompatibility with snapshot 20051220
======================================
The Postfix-with-Cyrus-SASL build procedure has changed. You now
need to specify -DUSE_CYRUS_SASL in addition to -DUSE_SASL_AUTH or
else you end up without any Cyrus SASL support. The error messages
are:
unsupported SASL server implementation: cyrus
unsupported SASL client implementation: cyrus
Major changes with snapshot 20051220
====================================
Plug-in support for SASL authentication in the SMTP server and in
the SMTP+LMTP client. With this, Postfix can support multiple SASL
implementations without source code patches. Some distributors may
even make SASL support a run-time linking option, just like they
do with Postfix lookup tables.
Hints and tips for plug-in developers are in the xsasl/README file.
For backwards compatibility the default plug-in type is Cyrus SASL,
so everything should behave like it did before. Some error messages
are slightly different, but these are generally improvements.
The "postconf -a" command shows what plug-in implementations are
available for the SMTP server, and "postconf -A" does the same for
the SMTP+LMTP client. Plug-in implementations are selected with
the smtpd_sasl_type, smtp_sasl_type and lmtp_sasl_type configuration
parameters.
Other new configuration parameters are smtpd_sasl_path, smtp_sasl_path
and lmtp_sasl_path. These are better left alone; they are introduced
for the convenience of other SASL implementations.
- Configurable text for (non)delivery status notifications.
- Support for multiple ISP accounts, implemented with sender-dependent
relayhosts and with sender-dependent SASL passwords.
- Enhanced status codes per RFC 2034. This enables much improved
error reporting with mail client programs, possibly in the user's
own language.
- Complete support for (non)delivery status notifications (DSN)
per RFC 346[1-4]. This also enables improved error reporting.
Reduce the number of patches needed by Postfix by using the subst
framework and also by explicitly specifying more default values for
Postfix parameters. Also pass -I/usr/pkg/include/sasl to the compiler
when building using Cyrus SASLv2, which allows me to remove the patches
that added an unnecessary USE_SASL2_AUTH check.
pkgsrc changes:
- install smtpd-policy script as example.
- adapot NetBSD 2.X and later.
- make local(8) handle EDQUOT as temporary error.
- enable RECEIVED_ENVELOPE_FROM.
Postfix changes:
20040324
Portability: ekkoBSD support by Philip Reynolds.
Files: makedefs, util/sys_defs.h.
20040325
Cleanup: smtp_skip_4xx_greeting and smtp_skip_5xx_greeting
functionality is moved from connection management to SMTP
protocol processing, so that Postfix now logs the server
response when a server refuses to provide service. Files:
smtp/smtp_connect.c, smtp/smtp_proto.c.
Cleanup: smtp_skip_4xx_greeting is no longer configurable;
it is now permanently turned on.
20040326
Workaround: in the trivial-rewrite server, turn on the code
to strip trailing "." while rewriting addresses, and change
the address resolver to strip trailing "." in a compatible
manner. This does not eliminate the problem that the SMTP
server may use a different address for recipient validation
than what the cleanup server uses for virtual alias mapping.
20040329
Bugfix: the SMTP server did not log client (and SASL)
information with the real-time content filter was enabled.
Files: smtpd/smtpd.c, smtpd/smtpd_sasl_proto.c.
Compatibility: smtpd_reject_unlisted_sender is turned off
by default, to avoid trouble with with in-house software
that sends out mail software with an unreplyable address.
20040331
Bugfix: postdrop should not abandon mail submission after
receiving a SIGHUP signal when SIGHUP was ignored by the
parent process. Victor Duchovni, Morgan Stanley. File:
postdrop/postdrop.c.
Bugfix: parsing bug in PgSQL dictionaries causing UNIX
sockets to be ignored. Liviu Daia. Files: global/dict*sql.c.
Performance: allow MySQL and PgSQL database connections to
be closed when idle for more than 1 minute; Liviu Daia.
Files: global/dict*sql.c.
20040401
Sanity: the SMTP server no longer accepts sender or recipient
addresses that end in the "@" null domain, as well as
addresses that rewrite into such a form. Specify
"resolve_null_domain=yes" to get the old behavior back.
File: trivial-rewrite/resolve.c.
20040402
Cleanup: added WARN action support for access maps, for
consistency with the WARN action in header and body checks.
File: smtpd/smtpd_check.c.
20040407
Bugfix: missing return statement at the end of the
FREE_MEMORY_AND_RETURN error handling macro. Adi Prasaja.
File: trivial-rewrite/resolve.c.
20040411
Future proofing: client_rate_time_unit is renamed to
anvil_rate_time_unit, so that it is no longer limited to
clients only. File: src/global/mail_params.h.
Cleanup: postalias and postmap now log problems to syslogd.
Files: postalias/postalias.c, postmap/postmap.c.
20040413
Feature: "postfix set-permissions" (re)sets ownership and
access permissions of Postfix files and directories.
Feature: "postfix upgrade-configuration" updates main.cf
and master.cf. This is for people who people copy over
their old files after installing a newer Postfix version.
Feature: HTML files are now optionally installed under
control of the html_directory configuration parameter.
Files: postfix-install, conf/postfix-files, conf/post-install.
Cleanup: README file installation is now optional. Files:
postfix-install, conf/postfix-files, conf/post-install.
20040414
Cleanup: references to sample-mumble.cf files removed,
conf/mumble_table files removed, new commands added to
conf/postfix-script.
Cleanups: function declared in but used as void, missing
include file, missing const qualifier, unused variable.
Matthias Andree. Files: bounce/bounce_notify_util.c,
bounce/bounce_service.h, postlog/postlog.c, smtpd/smtpd_check.c,
util/attr_scan64.c.
Bugfix: more robust version of SIGHUP test of 20040331.
Victor Duchovni, Morgan Stanley. File: postdrop/postdrop.c.
Safety: added NOCLOBBER qualifiers to local variables that
might be clobbered by longjmp(). Files: util/sys_defs.h,
smtp/smtp_proto.c, lmtp/lmtp_proto.c, smtpd/smtpd_check.c,
smtpstone/smtp-source.c.
Bugfix: sub-level Makefiles no longer turned on the extra
compiler warnings. Files: Makefile.in.*, makedefs.*.
20040415
Bugfix: the LMTP client attempted to reuse a connection
after timeout, causing protocol synchronization errors.
Reported by Rob Mueller. File: lmtp/lmtp.c.
20040416
Cleanup: non-delivery reports now include the original
recipient information. File: bounce/bounce_notify_util.c.
20040415-18
Typos: many documentation fixes by Rob Foehl.
20040418
Cleanup: "int" versus "const int" prototype mismatch between
the DICT sequence method prototype and possible implementations.
Files: util/dict_db.c, util/dict_dbm.c.
20040419
Bugfix: the code that rejects client/helo RESTRICTIONS with
smtpd_delay_reject=no looked at the wrong evidence and
rejected client/helo ACCESS MAP lookups instead. Michael
Tokarev. Files: smtpd/smtpd.c, smtpd/smtpd_check.c.
Bugfix: missing # in master.cf in optional submission
service.
20040420
Bugfix: smtpd logged the client too often. Michael Tokarev.
File: smtpd/smtpd.c.
Cleanup: client_event_status_update_time renamed to
anvil_status_update_time. Files: mantools/postlink,
proto/postconf.proto, anvil/anvil.c.
20040421
Workaround: allow pipelined SMTP clients to overshoot the
SMTP server recipient limit without triggering the server
hard error limit. The SMTP server does not count "too many
recipients" towards the hard error limit, as long as the
number of excess recipients stays within a configurable
overshoot limit (default: smtpd_recipient_overshoot_limit
= 1000). Solution in cooperation with Victor Duchovni.
Files: smtpd/smtpd.c, smtpd/smtpd_state.c, smtpd/smtpd.h.
20040502
Missing test for a never used flag (the problematic and
thus never completed INSPECT feature that doesn't re-inject
mail into Postfix). Victor Duchovni, Morgan Stanley. File:
virtual/virtual.c.
20040503
Bugfix: missing "sasl enabled" guard in the SMTPD policy
client. File: smtpd/smtpd_check.c.
support with tls+ipv6-1.22-pf-2.0.19-20040312.patch.gz, too.
20040302
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.
