Postfix snapshot 20010610 brings you the following benefits:

- A workaround for a bug in old versions of the CISCO PIX firewall
software 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.

RELEASE_NOTES and HISTORY information follows below the signature.

With me chairing the annual FIRST conference next week, this is
definitely the last code in a while, except for urgent bugfixes.

[RELEASE_NOTES]

Incompatible changes with snapshot-20010610
===========================================

The Postfix pipe delivery agent no longer automatically case-folds
the expansion of $user, $extension or $mailbox command-line macros.
Specify the 'u' flag to get the old behavior.

Major changes with snapshot-20010610
====================================

This release includes a workaround for a bug in old versions of
the CISCO PIX firewall software that caused mail to be resent
repeatedly to systems behind such a product.

The pipe mail delivery agent now supports proper quoting of white
space and other special characters in the expansions of the $sender
and $recipient command-line macros. This was necessary for correct
operation of the "simple" content filter, and is also recommended
for delivery via UUCP or BSMTP.

The pipe mail delivery agent now supports case folding the localpart
and/or domain part of expansions of the $nexthop, $recipient, $user,
$extension or $mailbox command-line macros. This is recommended
for mail delivery via UUCP. Bug: $nexthop is always case folded
because of problems in the queue manager code.

[HISTORY]

20010526

        newaliases no longer complains when an empty list is
        specified with the alias_database configuration parameter.
        File:  sendmail/sendmail.c.

20010529

        Workaround: old PIX firewall code messes up when the final
        ".<CR><LF>" at the end of DATA spans a packet boundary.
        When Postfix detects PIX SMTP fixup mode, Postfix flushes
        the output buffers before sending the final ".<CR><LF>".
        File:  smtp/smtp_proto.c.

20010530

        Portability: updated code for Mac OS X, accounting for the
        post-Beta changes. Code by Joe Block, UCF School of
        Optics/CREOL.

20010601

        Safety: postdrop turns off interrupts when cleaning up
        after interrupt. The additional safety does not hurt anyone.
        File: src/postdrop/postdrop.c.

20010607

        Safety: dropped the RFC 2821 compliant code that treats
        552 RCPT TO replies as 452. It created more problems than
        it solved. Files: smtp/smtp_proto.c, lmtp/lmtp_proto.c.

        Logging: the SMTP server now logs a warning if RBL lookups
        have problems other than "not found". file: smtpd/smtpd_check.c.

20010610

        Feature: address quoting and case folding flags for the
        pipe(8) mailer.
