SpamAssassin false positives on DATE_IN_FUTURE_96_Q?
by Gilbert E. Detillieux 23 Feb '16

23 Feb '16

I mentioned this problem at the last round-table session, but didn't get a solution, so I thought I'd post it here, just in case anyone has any suggestions to offer. I'm still seeing a whole bunch of false positives in SpamAssassin, since an update was installed in mid-September on a CentOS 5.7 system, for a rule called DATE_IN_FUTURE_96_Q, which is only supposed to be triggered when the "Date:" header has a date that is 4 days to 4 month ahead of the date in the "Received" header that has the _smallest_ difference in date. Here are the headers from the latest e-mail I've received with this false-positive. (I've stripped out irrelevant headers, for the sake of clarity and simplicity.) From topfivestories(a)messagent.itworldcanada.com Mon Nov 14 07:50:13 2011 Received: from mail.messagent.itworldcanada.com (mail.messagent.itworldcanada.com [207.112.10.80]) by palladium.cs.umanitoba.ca (8.13.8/8.13.8) with SMTP id pAEDoAxV028594 for <gedetil(a)cs.umanitoba.ca>; Mon, 14 Nov 2011 07:50:12 -0600 Date: Mon, 14 Nov 2011 08:50:13 -0500 X-Spam-Status: No, score=-0.3 required=5.0 tests=BAYES_00,DATE_IN_FUTURE_96_Q, HTML_MESSAGE,RP_MATCHES_RCVD autolearn=no version=3.3.1 X-Spam-Checker-Version: SpamAssassin 3.3.1 (2010-03-16) on palladium.cs.umanitoba.ca Note that I'm calling spamd via the spamass-milter on a system running sendmail. Note also, that in the above example, the only "Received" header was the one generated by my own server. (I've had other false positives, however, with multiple "Received" headers, all of which were within seconds of the time in the "Date" header.) Any ideas? -- Gilbert E.

Multiple Outgoing Interfaces Linux
by Robert Keizer 28 Aug '12

28 Aug '12

Hey hey, So I've got an annoying issue. I've got a Linux machine ( ubuntu 12.04 ) which has 3 physical interfaces into it. Two interfaces go to separate ISP's and one is internal. Because one of the upstream ISP's filters like crazy, specific traffic ( udp port 1194 ) needs to go out the non-default upstream provider. I've got that I need to use a combination of iptables with marking, and ip rules from iproute. I've been trying to follow this: http://unix.stackexchange.com/questions/21093/output-traffic-on-different-i… . Here's what I've got so far: iptables -> mangle -> prerouting : Mark packet ip table with default set to the alternate gateway ip rule to match marked packet to table I wasn't able to get the POSTROUTING rule to match. I'm still getting traffic on the primary link, which is then getting firewalled and blocked before it reaches its source. Has anyone had this issue before? Any help would be appreciated - I'm just banging my head against the wall.

Sunsolve ressurected (sort of)
by Adam Thompson 20 Aug '12

20 Aug '12

http://wesunsolve.net/ It's actually been around for a while, but I haven't seen anyone mention it. BigAdmin and all the other useful resources are still DOA thanks to Oracle, but a community effort has resurrected something very much like SunSolve. So if you still have Sun hardware, without a current service contract, check it out! -Adam Thompson athompso(a)athompso.net
