Date: Mon, 31 Oct 2011 09:34:28 -0400 Message-ID: <87ehxtuvx7.fsf@ironicdesign.com> User-Agent: Gnus/5.110018 (No Gnus v0.18) Emacs/23.3 (gnu/linux) MIME-Version: 1.0 Content-Type: text/plain Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Hi, Dave, Matti, https://issues.apache.org/SpamAssassin/show_bug.cgi?id=6429 has the details regarding the investigation in the SpamAssassin dev community that suggests that vger may be the only legitimate source of email that uses tabs in its headers---it is otherwise a very likely sign of a spam email. Although as you can see from the bug report's resolution, a modification has been done to the rule that matches to try and work around this---and thereby not unduly penalize mailing lists hosted on vger---it seems an even better solution would be if you were to actually change the zmailer configuration to not modify the headers of the emails passing through it. I don't know much about zmailer or your majordomo setup, but it seems like this would be a simple change that could make it easier for the many people on vger's lists who probably use SpamAssassin to keep their inboxes clean without undue false positives. Thanks for your time, Mike.
