- The postdrop mail submission command could die with SIGHUP and
abort mail submission. This was observed with mail from cron jobs.
- The MySQL client aborted with complaints about multiple attempts
to register the same lookup table. This was observed in the proxymap
daemon.
- As a workaround for agressive SMTP command pipelining clients,
the Postfix SMTP server now allows SMTP clients to overshoot the
SMTP server recipient limit without triggering the server hard
error limit, as long as the number of excess recipients stays within
a hard-coded overshoot limit of 1000. If you have such clients then
you also need to specify "smtpd_error_sleep_time = 0" or else
performance will be poor.
- The LMTP client attempted to reuse a connection after timeout,
causing protocol synchronization errors.
- The trivial-rewrite server could core dump after temporary table
lookup failure. This was not observed in Postfix 2.0.
- When mail is submitted at a high rate with the Postfix sendmail
command, the pickup daemon is keps busy long enough that it it
terminated by the watchdog timer (a feature that prevents Postfix
from locking up permanently).
- Malformed addresses in SMTP commands could result in table looks
with zero-length search strings, causing trouble with NIS lookups.
- A change in the line reading routines caused unexpected results
with lines ending in EOF. This change is undone.
- A portability problem with the test command ("test -e" is not
supported on older systems, while "test -f" does the job).
- Portability to MacOSX: Bind8 compatibility, core dumps in mailq
and postdrop, and changes in netinfo support.
- Elimination of some DNS lookup problems in third-party library
routines (typically resulting in localhost not being found).
- More agressive delivery to sites that defer a lot of mail.
- Correction of a few obscure error messages.
- Several small documentation fixes.
- Minor fixes for robustness problems that no-one has experienced.
"auxprop".
* Modify the package so that the smtpd.conf file is initially stored
with the other example files and copied over to its true location
via CONF_FILES. This allows modifying the postfix installation to
use some other SASL authenticaion method, e.g. PLAIN with saslauthd
through TLS.
* Only allow using one SASL library or the other, and prefer SASL2 to
SASL1.
- After "postfix reload", the master daemon now warns when the
inet_interfaces parameter setting has changed, and ignores the
change, instead of passing incorrect information to the smtp
server.
- After the postdrop command change with Postfix 2.0.11, the postcat
command no longer recognized "maildrop" queue files as valid.
- Mail could bounce when two messages were delivered simultaneously
to a non-existent mailbox file. The safe_open() code that prevents
race condition exploits will now try a little harder when it
actually encounters a race condition.
- Updated the IPv6 patch.
- Stricter smtpd input checks rejected invalid addresses starting with @.
- Stricter postdrop input checks broke "sendmail -bs".
- New "postcat -q" (search the queue for the named file) support
from snapshot release because I can no longer see people suffer.
- Allow <@site,@site:address> route addresses in SMTP commands.
This address form was deprecated years ago.
- "sendmail -q<time>" without -bd option now exits immediately,
instead of waiting for input and screwing up system boot sequences.
- The Postfix LMTP client used the wrong service name, causing
trouble with SASL 2.1.13.
- Turned off non-blocking write to pipe because too many systems
gave an unexpected write() result, causing partial delivery of
messages to commands like procmail.
- Ugly but harmless warnings from nqmgr after "postsuper -r" to
requeue files that already had some recipients delivered.
- The proxy_read_maps parameter did not recognize "," as separator.
- The local delibery agent now defers delivery after .forward etc.
file read error.
- The message_size_limit was applied when running "newaliases",
so that the result alias database could be truncated on systems
with very small message size limits.
The official release changes for bugfixes and portability issues only.
as samples, either by the user or by bsd.pkg.install.mk.
- Correctly handle configuration files, that is, avoid touching the conf
directory directly.
- Use OWN_DIRS to handle the spool directory.
- Run post-install through an INSTALL script.
- Sort PLIST after all these changes.
- Bump PKGREVISION to 1.
- The SMTP client did not deliver a partial last line when someone
submitted 8BITMIME mail not ending in newline via /usr/sbin/sendmail
while MIME input processing was turned off, and MIME 8bit->7bit
conversion was requested upon delivery.
- Postfix processes now abort when given a net/mask pattern with
a non-zero host portion (for example, 168.100.189.2/28), instead
of risking to become an open mail relay.
- Workaround for file system clock drift that caused Postfix to
ignore new mail (this could happen with queue file systems mounted
from a server).
