[Mimedefang] MIMEDefang 2.34-BETA-4 or a patch for 2.33 fixed Received: problem

[David F. Skoll]

Hi,

There is in fact a bug in the way MIMEDefang hands off a Received: header
to SpamAssassin.

You can either download 2.34-BETA-4 from
http://www.mimedefang.org/node.php?id=1 or apply this patch to 2.33 and
rebuild 2.33:

     # Synthesize a "Return-Path" and "Received:" header
     my @sahdrs;
     push (@sahdrs, sprintf("Return-Path: %s\n", $Sender));
-    push (@sahdrs, synthesize_received_header());
+    my $hdr;
+    $hdr = synthesize_received_header();
+    my $line;
+    foreach $line (split(/\n/, $hdr)) {
+       push (@sahdrs, "$line\n");
+    }

     unshift (@msg, @sahdrs);

Please note that 2.34-BETA-4 includes a lot of stuff that isn't ready
yet and is #ifdef'd out (the FFR_SENDMAIL_TCP_MAP).  Don't ask me what
it's for; all will be revealed. :-)

It also drops support for non-multiplexor mode.

Regards,

David.

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

Changelog for 2.34-BETA-4 follows:

2003-05-27  David F. Skoll  <dfs at roaringpenguin.com>

	* mimedefang.pl.in (spam_assassin_mail): Fix the way the
	synthesized Received: header was handed to SpamAssassin.

	* configure.in: Changed default location of quarantine directory
	to /var/spool/MD-Quarantine.  *** NOTE INCOMPATIBILITY ***
	Use --with-quarantinedir=/var/spool/MIMEDefang if you want the
	old behaviour.

	* mimedefang.c: Removed support for non-multiplexor operation.
	It is now mandatory to use the multiplexor.
	*** NOTE INCOMPATIBILITY ***

2003-05-26  David F. Skoll  <dfs at roaringpenguin.com>

	* configure.in, Makefile.in, mimedefang.pl.in, README.SOPHIE:
	Improved Sophie support, courtesy of Jason Englander.

2003-05-25  David F. Skoll  <dfs at roaringpenguin.com>

	* Makefile.in: "make install" target obeys DESTDIR (as well
	as former RPM_INSTALL_ROOT) to change installation root.

2003-05-21  David F. Skoll  <dfs at roaringpenguin.com>

	* MIMEDefang 2.34-BETA-3

	* mimedefang.pl.in: Check for socket errors when talking to
	daemonized virus scanners like Sophie, Trophie, Clamd and
	CarrierScan, and return tempfail on error.  Problem noted
	by Chris Stromsoe and Dave Shrimpton.

	(relay_is_blacklisted): Rather than just returning true or
	false, we return the actual DNS lookup value (like "127.0.0.2")
	if a host is in a DNS-based blacklist.  Feature requested by
	Matthew Hall.

	* Tempfail codes default to 451/4.3.0 rather than 450/4.7.1.
	These new codes are more consistent and in line with
	RFCs 2821 and 1893.

2003-05-14  David F. Skoll  <dfs at roaringpenguin.com>

	* configure.in: Because of SCO's disgusting behaviour,
	MIMEDefang will refuse to build on SCO UNIX or SCO Linux
	unless you supply the --enable-running-on-scummy-sco configure
	option.

2003-05-12  David F. Skoll  <dfs at roaringpenguin.com>

	* mimedefang-filter.5.in: Documented md_syslog.  md_syslog
	is now an officially-supported API function.

	* mimedefang.c (mfconnect): Do not use strncpy in
	potentially-unsafe way (Dirk Mueller)

	* mimedefang.c, mimedefang.pl.in: Allow Perl filters to specify
	SMTP reply codes (4xx, 5xx) and DSN status codes (4.x.y, 5.x.y)
	(Suggested by user "jkohan" on the MIMEDefang Web site.)

	* mimedefang.pl.in: md_check_against_smtp_server returns the
	same SMTP reply code and DSN status as the forwarding server
	(rather than its own codes on failure.)
