+From: Samuel Tardieu <sam@rfc1149.net>
+Subject: Bug#300175: Patch for clamav/clamsmtp
+Date: Mon, 21 Mar 2005 11:07:48 +0100
+To: 300175@bugs.debian.org
+Cc: erwan@rail.eu.org
+Reply-To: sam@rfc1149.net
+
+On recent glibc, files created with mkstemp() are created with mode
+0600. If the mode is not changed, there is no way for another user to
+read the temporary file, regardless of the users' respective groups.
+
+This patch allows users in the same group to read the temporary files.
+This should solve Erwan's problem, and certainly has solved mine:
+
+Sam
+
+PS/ older glibc used to create the file in 0666 mode, which may explain
+    why not everyone has this problem
