This patch provides an emergency band-aid for the next wave of
MicroSoft email worms, fixes one bug, and makes external content
filtering a bit more robust.
- Feature: specify "body_checks = regexp:/etc/postfix/body_checks"
for an emergency content filter that looks at non-header lines
one line at a time (including MIME headers inside the message
body). This feature uses the same syntax as the header_checks
patterns. Details in conf/sample-filter.cf.
This feature is also available in Postfix snapshot 20000528.
- Bugfix: the masquerade_exceptions feature was case sensitive.
- Robustness: upon receipt of mail, Postfix maps MAILER-DAEMON@myorigin
sender address back into the magic null string, which prevents
mail from looping after processing by an external content filter.
format and generates a set of cross-referenced HTML documents. Each file that
is created represents a separate message in the mail archive and contains
links to other articles, so that the entire archive can be browsed in a
number of ways by following links. Archives generated by Hypermail can be
incrementally updated, and Hypermail is set by default to only update
archives when changes are detected.
- RFC 822 requires the presence of at least one destination
message header. Postfix now generates a generic "To:
undisclosed-recipients:;" message header when no destination
header is present. The header content is specified with the
new undisclosed_recipients_header parameter.
- Postfix now understands <(comment)> as SMTP MAIL FROM address,
because some broken software needs it. Postfix rejects such
illegal address forms with "strict_rfc821_envelopes = yes".
- Configuration parameters for one mysql dictionary would become
default settings for the next one. This patch was merged into
the development Postfix version a while back but apparently
that version was on a dead branch. Update by Scott Cotton.
- Some Postfix delivery agents would abort on addresses of the
form `stuff@.' which could unfortunately be generated locally.
- With local delivery, Postfix could insert > or . into the middle
of very long lines.
- SMTP sessions could time out when the remote client attempted
to deliver to a large number of rejected recipients. The SMTP
server now flushes unwritten output in-between tarpit delays,
to avoid protocol timeouts in pipelined SMTP sessions.
- Postfix would incorrectly reject domain names with adjacent `-'
characters.

* fix a tempnam() usage in the patch
No fake or flavours support - this may get done if I learn enough,
quickly enough. Will not build as a real package just now. Working on
it.
The port and package install _exactly_ the same as a manual qmail install,
except for the addition of a /var/qmail/setup directory where the setup
scripts are copied.
Therefore the following should apply: http://cr.yp.to/qmail/dist.html
- clean-up pkg/INSTALL (qmail now builds as non-root, if qmail accounts exist)
The mysql and postfix ports could also use the create_user and/or
create_group shell functions, as they do a bit more error-checking.
- add obsd tags to INSTALL/DEINSTALL
- fix mastersite
- explicit warning that qmail does not automagically work after install
Thoroughly unsubtle, most mkdir -p should probably be INSTALL* at
*install stage, and echo/ECHO_MSG is somewhat unsorted.
It's quite possible I missed a few automated changes...

one using exim ?
Changes are in doc/ChangeLog and are all bug fixes - no new features.
-- Info from Wietse --
Patch 04 fixes one old problem that never happened, and fixes two
new problems introduced with patch 03, one of which urgent. The
problems were found as I was reorganizing the cleanup daemon code.
The too long header fix in patch 03 loses mail when a header is
found too long, and when that mail is't posted with "sendmail -t".
Actually the mail is not lost. The queue file stays in the incoming
queue, as a file with mode -rw-------.
In order to have such mail delivered, chdir into the directory
/var/spool/postfix/incoming, and look for mode -rw------- queue
files that are older than a few minutes (ls -lt|more) and chmod +x
those old mode -rw------- queue files.
DO NOT CHMOD +X ALL INCOMING QUEUE FILES because that causes Postfix
to discard messages that are still being received.
Postfix version 19991231 patchlevel 03 fixes low-priority defects
and provides workarounds for unusual conditions.
- Workaround to prevent one site with a huge backlog from blocking
all other deliveries. This is controlled by a new configuration
parameter qmgr_site_hog_factor (default: 90 percent) that limits
how much in-memory queue manager resources a site can claim.
- Workarounds for the most likely problems that will happen when
running the Postfix queue on top of NFS.
- The SMTP server did not look in the relocated table and would
report "User unknown" rather than letting the mail bounce the
way it is supposed to be.
- When requested to extract recipients from message headers, Postfix
now insists that no message header exceeds the header size limit.
This prevents Postfix from inadvertently disclosing Bcc: addresses.
fastforward handles qmail forwarding according to a cdb database. It can
create forwarding databases from a sendmail-style /etc/aliases or from
user-oriented virtual-domain tables.
