Subject: postfix-alpha-19990315 pre-release
To: postfix-announce at postfix.org
Date: Mon, 15 Mar 1999 22:37:11 -0500 (EST)

A preliminary Postfix release, postfix-alpha-19990315 will be
available soon from ftp//ftp.porcupine.org/mirrors/postfix-release/
and mirror sites.

I will wait for a few days for feedback, after which I will finish
an official Postfix beta release.

There is a lot of code in the pipeline: the backlog extends well
into January 1999.

Below is an extract from the preliminary RELEASE_NOTES file.

Incompatible changes with postfix-alpha-19990316:
=================================================
 
- You MUST install the new version of /etc/postfix/postfix-script.
 
- The pipe mailer "flags" syntax has changed. You now explicitly
have to specify the R flag in order to generate a Return-Path:
message header (this is needed by, for example, cyrus).
 
Major changes since postfix-beta-19990122-pl01:
===============================================
 
A detailed list is given in the HISTORY file.
 
- By default, undeliverable bounce messages are no longer sent to
postmaster. Specify "notify_classes = 2bounce..." to get copies of
double bounces. Specify "notify_classes = bounce..." to get copies
of normal and double bounces.
 
- Improved LDAP client code by John Hensley of Merit Network, USA.
See LDAP_README for details.
 
- Perl-compatible regular expression support for lookup maps by
Andrew McNamara, connect.com.au Pty. Ltd., Australia..  Example:
check_recipient_access pcre:/etc/postfix/sample-pcre.cf. Regular
expressions provide a powerful tool for SMTP access control, address
rewriting, and message routing. See PCRE_README for details.
 
- With "delay_warning_time = 4", Postfix informs senders when mail
has not been delivered after 4 hours. Initial version of the code
by Daniel Eisenbud, University of California at Berkeley. In order
to receive postmaster copies of such warnings, specify "notify_classes
= delay...".
 
- Several changes to improve Postfix behavior under worst-case
conditions (too much incoming mail, frequent restarts/reloads, lots
of intermittent connectivity problems, SMTP servers that become
comatose after receiving QUIT).
 
- More configurable local delivery: "mail_spool_directory" to
specify the UNIX mail spool directory; "mailbox_transport" to
delegate all mailbox delivery (including non-UNIX users) to another
message transport, e.g. cyrus, without losing aliases and .forward
processing. See config/main.cf and config/master.cf.
 
- More NFS-friendly mailbox delivery. The local delivery agent
now avoids using root privileges where possible.
 
- mydestination can now be an empty string. Be sure to set up a
route to prevent mail from looping.
 
- New "postsuper" utility to clean up stale files from Postfix
queues.
 
- Workaround for BSD select() collisions that cause performance
problems on large BSD systems.
 
- Use "hash:/etc/aliases, unix:passwd.byname, $virtual_maps" in
smtpd access tables to recognize known local users. We're almost
there with stopping unknown users at the RCPT TO command.
 
- Several questionable but useful features to capture mail:
"always_bcc = address" to capture a copy of every message that
enters the system, and "luser_relay = address" to capture mail for
unknown recipients (does not work with "mailbox_transport).
 
- The SMTP server now has reject_non_fqdn_{hostname,sender,recipient}
restrictions to reject non-FQDN arguments in HELO, MAIL FROM and
RCPT TO commands.
 
- Several questionable controls that can help to get mail going:
specify "smtp_skip_4xx_greeting = yes" to skip SMTP servers that
greet with 4XX, "ignore_mx_lookup_error = yes" to look up an A
record when a DNS server does not respond to an MX query.
