Postfix official release 20010228 Patch 05 fixes a problem with
canonical and virtual address rewriting, and with the parsing of
malformed address extensions.

Bugfix: updated LDAP client module from LaMont Jones, HP.
This also introduces new LDAP query filter patterns: %u
(address localpart) and %d (domain part). Files:
conf/sample-ldap.cf, util/dict_ldap.c.
20010729
Bugfix: recursive smtpd_whatever_restrictions clobbered
intermediate results when switching between sender and
recipient address restrictions. Problem found by Victor
Duchovni, morganstanley.com. In order to fix, introduced
address resolver result caching, which should also help to
speed up sender/recipient address restriction processing.
Bugfix: the not yet announced DUNNO access table lookup
result did not prevent lookups with substrings of the same
lookup key. Found by Victor Duchovni, morganstanley.com.

Robustness: trim trailing whitespace from regexp and pcre
right-hand sides, for consistency with DB/DBM tables.
Files: util/dict_pcre.c, util/dict_regexp.c.
20010731
Robustness: eliminate duplicate IP addresses after expansion
of hostnames in $inet_interfaces, so that Postfix does not
suddenly refuse to start up after someone changes the DNS.
- A workaround for a bug in old versions of the CISCO PIX firewall software
l that caused mail to be resent repeatedly to systems behind such a product.
The same workaround will be folded into the "stable" release when time
permits.
- A much enhanced pipe delivery agent with flags to control case folding of
the $nexthop, $recipient, $user, $extension or $mailbox command-line macros.
- A much enhanced pipe delivery agent with proper quoting of white space and
other special characters in the expansions of the $sender and $recipient
command-line macros. This is necessary for correct operation of the "simple"
content filter, among others.
- Retraction of one RFC2821-induced change that was causing more problems
than it solved.
Postfix official release 20010228 patch 03 fixes all known problems that were
also fixed with snapshot 20010525.
The official Postfix release does not change except for bugfixes. New
features are introduced in Postfix snapshots; the snapshots eventually evolve
into the next official release.
Only only major fix is for a memory leak in the LDAP client module. If you do
not use LDAP, then there is no urgent need to apply the patch.
A fully patched version will be made available via the usual sites listed on
the www.postfix.org web site.
- Many little revisions of little details in the light of the new RFC 2821
and RFC 2822 standards. RFC features considered less urgent or less useful
are discussed in source code comments. See the RELEASE_NOTES for possible
incompatibilities.
- A much enhanced postsuper queue maintenance tool that can fix Postfix
queues restored from another machine or from backup. The postsuper tool
corrects file names when a file name does not match the message file
inode number. My respect has doubled for people who write fsck-like programs.

Postfix Release 20010228 Patchlevel 01 includes patches that were
sent to the list in the last month, some portability enhancements,
and updated documentation.
- The flush daemon complained when Postfix was deferring mail
for user@[ip.address], and aborted with a panic when deferring
mail to user@a.domain.name (one-letter subdomain name).
- The LMTP connection caching did not work for destinations that
start with inet: or unix:.
- The cleanup server stalled when mail exceeded the queue file
size limit by a small amount. The sender was not informed of
the file size problem and kept sending the mail repeatedly.
- Mail address headers with newline inside (comment) caused
Postfix to emit a backslash before the end of line.

The mailbox file size limits for the local and virtual delivery
agents can be disabled by setting mailbox_size_limit and/or
virtual_mailbox_limit to zero.
