patchlevel 11 -> 12
While processing massive amounts of one-recipient mail, the Postfix
queue manager could deadlock for 10 seconds while sending a bounce
message. In order to remedy this, all queue manager bounce send
requests are now executed asynchronously. This problem was reported
by El Bunzo (webpower.nl) and by Tiger Technologies (tigertech.com).
Major changes with postfix-19991231-pl08:
=========================================
Specify "body_checks = regexp:/etc/postfix/body_checks" for a quick
and dirty emergency content filter that looks at non-header lines
one line at a time (including MIME headers inside the message body).
Details in conf/sample-filter.cf.
Incompatible changes with postfix-19991231-pl07:
================================================
As required by RFC 822, Postfix now inserts a generic destination
message header when no destination header is present. The text is
specified via the undisclosed_recipients_header configuration
parameter (default: "To: undisclosed-recipients:;").
Create the /var/spool/postfix on install so that "postfix check" can
create the directories below it.
Create /etc/postfix/postfix-scrip on "make install".
Make the library Makefiles DTRT on systems that don't understand MKXXX=no.
Remover owner write permission from "maildrop" binary.
Adjust offsets in a couple of patches.
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.
