===================

    Incompatible changes with Postfix 2.3.7
    ---------------------------------------

    Postfix no longer inserts an empty-line header/body separator into
    malformed MIME attachments, to avoid breaking digital signatures.

    This change introduces ambiguity. Postfix still treats the remainder
    of the attachment as body content; header_checks rules will therefore
    not detect forbidden MIME types inside a message/rfc822 attachment.

    With the empty-line header/body separator no longer inserted by
    Postfix, other software may process the malformed attachment
    differently, and thus may become exposed to forbidden MIME types.


HISTORY file:
=============

20070104

	Bugfix (introduced Postfix 2.3): when creating an alias map
	on a NIS-enabled system, don't case-fold the YP_MASTER_NAME
	and YP_LAST_MODIFIED lookup keys. This requires that an
	application can turn off case folding on the fly. This is
	a point fix. A complete fix requires updates to other map
	types and to the proxymap protocol, which is too much change
	for a stable release.  Files: postalias/postalias.c,
	util/dict_db.c, util/dict_dbm.c, util/dict_cdb.c.

20070112

	Bugfix (introduced 20011008): after return from a nested
	access restriction, possible longjump into exited stack
	frame upon configuration error or table lookup error.  Victor
	Duchovni.  Files: smtpd/smtpd_check.c.

	Workaround: don't insert empty-line header/body separator
	into malformed MIME attachments, to avoid breaking digital
	signatures. This change introduces ambiguity. Postfix still
	treats the remainder of the attachment as body content;
	header_checks rules will not detect forbidden MIME types
	inside a message/rfc822 attachment.  With the empty-line
	header/body separator no longer inserted by Postfix, other
	software may process the malformed attachment differently,
	and thus may become exposed to forbidden MIME types.  This
	is back-ported from Postfix 2.4. File: global/mime_state.c.

20070118

	Bugfix: match lists didn't implement ![ipv6address].  Problem
	reported by Paulo Pacheco. File: util/match_list.c.
