Neue version vom postfix ist draussen ... postfix-alpha-19990315.tar.gz ftp://ftp.rfc822.org/pub/mirror/postfix/postfix-alpha-19990315.tar.gz Flo ----- Forwarded message from Wietse Venema <wietse@porcupine.org> ----- Subject: postfix-alpha-19990315 pre-release To: postfix-announce@postfix.org Date: Mon, 15 Mar 1999 22:37:11 -0500 (EST) Message-Id: <19990316033711.F252918C45@fist.porcupine.org> From: wietse@porcupine.org (Wietse Venema) 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. Wietse 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. ----- End forwarded message ----- -- Florian Lohoff flo@rfc822.org +49-5241-470566 Good, Fast, Cheap: Pick any two (you can't have all three).
