Hi,

MIMEDefang 2.20 is available at http://www.roaringpenguin.com/mimedefang/

Major changes:

o Do not fork/exec "/bin/rm" to clean up working directories.  Instead,
  use an internal C routine.  This should improve performance.

o Many functions which copied files (action_quarantine and friends) now
  try a hard-link first, and fall back to copy only if that fails.  If you
  keep your spool and quarantine directories on the same disk partition,
  this change can improve performance a lot.

o Tightened up the default rules (thanks to Nik Clayton) to recognize
  more extensions and be pickier about the CLSID attack.

Full changelog relative to 2.19 appended.

Regards,

David.

	* Version 2.20 RELEASED

	* mimedefang.pl.in: Quarantine functions try to make a
	hard link when copying messages; fall back to actual copy
	if hard link fails.  This can greatly improve performance.

	* examples/suggested-minimum-filter-for-windows-clients:
	More "dangerous" extensions; tighter conditions for suspecting
	CLSID attack (thanks to Nik Clayton).

2002-09-04  David F. Skoll  <dfs at roaringpenguin.com>

	* mimedefang.pl.in:  The "-features" output includes
	MIMEDefang version as well as versions of selected Perl modules.

2002-08-29  David F. Skoll  <dfs at roaringpenguin.com>

	* examples/suggested-minimum-filter-for-windows-clients:
	Added three new "dangerous" extensions: .app, .fxp and .prg.
	Thanks to Marco Berizzi.

	* examples/suggested-minimum-filter-for-windows-clients:
	Allow filenames like "foo at bar.com,innocuous.txt" rather
	than choking on the ".com," part.

	* mimedefang.c (cleanup): Use an internal C implementation of
	"rm -rf" rather than forking and execing /bin/rm.  This should
	improve performance on heavily-loaded systems.

	* configure.in: Added --with-user=LOGIN configure-time option.
	We do not check for existence of this user at configure-time,
	because it would complicate building of RPM.

	* RPM creates "defang" user when installed.

	* Cleaned up configure script to use AC_MSG_xxx instead of echo
	in a lot of places.
