Incompatible changes with postfix-19990906
==========================================
- On systems that use user.lock files to protect system mailboxes
against simultaneous updates, Postfix now uses /file/name.lock
files while delivering to files specified in aliases/forward/include
files. This is a no-op when the recipient lacks directory write
permission.
- The LDAP client code no longer looks up a name containing "*"
because it could be abused. See the LDAP_README file for how to
restore previous behavior.
- The Postfix to PCRE interface now expects PCRE version 2.08.
Postfix is no longer compatible with PCRE versions prior to 2.06.
Major changes with postfix-19990906
===================================
Several bugfixes, none related to security. See the HISTORY file
for a complete list of changes.
- Postfix is now distributed under IBM Public License Version 1.0
which does not carry the controversial termination clause. The new
license does have a requirement that contributors make source code
available.
- INSTALL.sh install/upgrade procedure that replaces existing
programs and shell scripts instead of overwriting them, and that
leaves existing queue files and configuration files alone.
- The ugly Delivered-To: header can now be turned off selectively.
The default setting is: "prepend_delivered_header = command, file,
forward". Turning off the Delivered-To: header when forwarding
mail is not recommended.
- mysql client support by Scott Cotton and Joshua Marcus, Internet
Consultants Group, Inc. See the file MYSQL_README for instructions.
- reject_unauth_destination SMTP recipient restriction that rejects
destinations not in $relay_domains. Unlike the check_relay_domains
restriction, reject_unauth_destination ignores the client hostname.
By Lamont Jones of Hewlett-Packard.
- reject_unauth_pipelining SMTP *anything* restriction to stop mail
from spammers that improperly use SMTP command pipelining to speed
up their deliveries.
- Postfix "sendmail" now issues a warning and drops privileges if
installed set-uid root.
- No more duplicate delivery when "postfix reload" is immediately
followed by "sendmail -q".
- No more "invalid argument" errors when a Postfix daemon opens a
DB/DBM file while some other process is changing the file.
- Portability to the Mac OS X Server, Reliant Unix, AIX 3.2.5 and
Ultrix 4.3.
but calculated every time bsd.prefs.mk is read. Correct the
situation, and only calculate these when they are needed.
Also save a few more cycles by hardcoding the LOWER_OPSYS values for
known operating systems, rather than using expensive shell echo and tr
commands every time bsd.prefs.mk is read.
pages that are installed will be gzip-compressed, if MANZ is set, or
not if MANZ is not set. If the package uses bsd-style .mk files, the
variable MANCOMPRESSED_IF_MANZ should be set to a value of "yes" in
the package Makefile. This replaces the previous method of specific
inclusion of bsd.prefs.mk, followed by a check for MANZ and
conditional assignment of MANCOMPRESSED.
Add appropriate documentation, and change all necessary ocurrences in
package Makefiles.
path bugs:
- pass OPSYS to Makefile.inc, don't hardcode NETBSD1
- command_directory, daemon_directory, share_directory, man_directory
were hard-coded to /usr/pkg, bleh!
- and so was the ROOT_PATH.
