Bumped the default mailbox file size limits to 50MB.
20010202
Bugfix: fixed the way the master resets the file size limit
to avoid problems when a Postfix daemon updates a queue
file. The file size limit is now increased to INT_MAX if
it is smaller than INT_MAX, so that it is less likely to
interfere than the old setting of message_size_limit.
Feature: disable mailbox size limits for the local and
virtual delivery agents by setting mailbox_size_limit or
virtual_mailbox_limit to zero.

Apart from bugfixes this is expected to become the first non-beta
Postfix release.
Major changes with snapshot-20010202
====================================
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.
Incompatible changes with snapshot-20010128
===========================================
If this release does not work for you, you can go back to a previous
Postfix version without losing your mail, subject to the "incompatible
changes" listed for previous Postfix releases below.
REJECT in header/body_checks is now flagged as policy violation
rather than bounce, for consistency in postmaster notifications.
The mailbox size limit for local delivery is no longer controlled
by the message_size_limit paramater, but by a separate parameter
called mailbox_size_limit (default: 20MBytes).
New mailbox size limit for local delivery (default: 50MBytes). This
limit affects all file write access by the local delivery agent or
by a process run by the local delivery agent. The purpose of this
parameter is to act as a safety for run-away software. It cannot
be a substitute for a file quota management system.
The default RBL (real-time blackhole lists) domain examples have
been updated from *.vix.com to *.mail-abuse.org.
