Bugfix: the mail_addr_map() fix was almost but not quite
right. It took two really clever people and several iterations
of email to really fix the mail_addr_map() problem. Thanks

Cleanup: Postfix no longer flushes the whole deferred queue

after an ETRN request for a random domain name (i.e. a

server instead replies with "459 service unavailable".

Bugfix: there was a minute memory leak when an smtpd access
restriction is misconfigured. File: smtpd/smtpd_check.c.
Open problems:
Minor: The $process_id_directory setting is not used anywhere
in Postfix. Problem reported by Michael Smith, texas.net.
Medium: address rewriting should be configurable for envelopes
and headers.

Incompatible changes with snapshot-20011008
===========================================
Postfix no longer flushes the whole queue after an ETRN request
for a random domain name. Requests for random domain names are now
The Postfix SMTP server now rejects requests with a generic "try
again later" status (451 Server configuration error) when it detects
an error in smtp_{client,helo,sender,recipient,etrn}_restrictions
settings. More details about the problem are logged to the syslogd;
sending such information to random clients would be inappropriate.
Postfix no longer flushes the entire mail queue after receiving an
ETRN request for a random domain name. Requests for random domain
names (i.e. names that do not match $fast_flush_domains) are now
rejected instead.
The permit_mx_backup feature has changed. It accepts mail when the
local machine is listed in the DNS as MX relay host for the given
destination. The optional permit_mx_backup_networks parameter can
further require that the primary MX hosts for the given destinations
match specific network blocks. This optional restriction is off by
default.
The permit_mx_backup behavior is back to the behavior before snapshot
20010808. It accepts mail whenever the local MTA is listed in the
DNS as an MX relay host for a destination, even when you never gave
permission to do so. To restrict use of this feature, specify
network address blocks via the permit_mx_backup_networks parameter.
This requires that the primary MX hosts for the given destination
match the specified network blocks.
