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.

Winnipeg Harvest donations from December meeting - thank you!
by athompso＠muug.mb.ca 04 Apr '12

04 Apr '12

Thanks to the generosity of our members, we were able to donate three large boxes’ worth of non-perishable food items to Winnipeg Harvest in December 2010. The text of the thank-you letter we just received (see attached) is as follows: January 5, 2011 Manitoba UNIX User Group Attn: Adam Thompson Dear Friends of Harvest, We here at Winnipeg Harvest want to thank the Manitoba UNIX User Group for your support of helping those less fortunate in our community. Over the last few months 743 pounds of food was donated to the food bank. Your donations will go into hampers that will help Winnipeg Harvest feed more than 58,000 people each month, half of those being children. On behalf of the entire team at Winnipeg Harvest, thank you for helping us fight hunger and feed hope in Manitoba. We look forward to working with you again in the future. If I can ever be of assistance, please don’t hesitate to contact me by phone at 982-3670 or by email at tori(a)winnipegharvest.org. Yours truly, Tori Webber Development Associate Winnipeg Harvest Inc. So, thanks again. See you all in another six (6) days, at our next meeting on January 11th, 2011. -Adam Thompson athompso(a)muug.mb.ca

FW: CIRA consultation on accented domain names
by Adam Thompson 21 Jan '12

21 Jan '12

CIRA, the .ca domain registrar, is proposing to allow a restricted subset of IDNs (Internationalized Domain Names) in order to support accented French characters in domain names. If you speak or write in French, this will likely affect you at some point. If you use any .ca domain names, this may still affect you, although probably in less direct ways. Speaking only on my own behalf (specifically: MUUG does not currently have an official position on the matter), I encourage anyone who cares about our national ccTLD to review the information CIRA has made available, form an opinion, and voice your opinion promptly. IMHO, this is even more important than voting – if we choose poorly in an election, we have the opportunity to collectively change our minds in five years or less (usually four), whereas the CIRA IDN policy is likely to affect Canadians and Canada itself for decades to come. There’s no automatic reconsultation in four years, and there’s no built-in review process for decisions taken by NGOs like CIRA. In fact, once a decision like this is made, there may be no recourse at all if we collectively decide we don’t like the result. It’s obvious to me that CIRA is expecting to make a tidy sum of money by doing this (otherwise I believe they would be taking a different direction altogether), which I believe is OK as long as the internet-using-public’s interests are still served. I already have an opinion on the matter, and I’ll be making a submission. CIRA is effectively an NGO [I can’t tell what their legal status is right now], and they’re voluntarily doing the right thing by consulting the public – they’re not obligated to do so – but that consultation process is only effective if CIRA members express their opinions. Please express your opinion. -Adam Thompson <mailto:athompso@athompso.net> athompso(a)athompso.net From: CIRA / ACEI [mailto:communications.ca@cira.ca] Sent: Thursday, September 22, 2011 10:29 To: athompso(a)athompso.net Subject: CIRA consultation on accented domain names <http://sm01.ott.cira.ca:80/track?mailingid=4906&messageid=3713&databaseid=2…> Consultation on accented doman names <http://www.cira.ca/assets/Images/mass-mail/CA-logo.jpg> Have your say: Join CIRA’s consultation on accented domain names _____ Dear Adam Thompson, As part of our effort to continually enhance the .CA domain, the Canadian Internet Registration Authority (CIRA) is considering the implementation of French character Internationalized Domain Names (IDNs) at the second level (to the left of the dot). An Internationalized Domain Name is simply a domain name that contains characters other than a-z, 0-9 or hyphens. CIRA is planning the addition of the following accented characters to .CA domain names: * é, ë, ê, è * à, â * ô * ù, û, ü * ç * î, ï This means you could soon see domain names like préside.ca, grâce.ca, etc. Before we can implement IDNs, CIRA is preparing a framework that will help us create a policy for launching accented domain names. As a Registrant, we are seeking your input on our proposed framework. On September 20, 2011, CIRA opened a public consultation concerning our planned launch of IDNs. The feedback received from .CA holders like you, as well as our Members, Registrars and other stakeholders, will help us shape the final IDN launch policy.

Anyone here use it and wouldn't mind the imposition of demo'ing it? Having used pine for well at least a decade the Maildir patch is largely umzaintained since I updated/maintained it back in 4.3. I keep hearing mutt is better and I'd like to see why and I'm sure others on this list would too. -- Sean (mobile)

a un*x admin tool paging by default
by Trevor Cordes 17 Dec '11

17 Dec '11

Am I the only one this ticks off (enough to make a bugzilla)? https://bugzilla.redhat.com/show_bug.cgi?id=768601 Only the devil himself (or Windows people) would page output by default in an admin tool. The only other un*x app I've ever seen this with is postgres's interactive command line. Go to the bugzilla (if you have an account) and cc: yourself (equivalent to voting at RH bugzilla it would seem).

boot / fsck debug shells
by Trevor Cordes 14 Dec '11

14 Dec '11

Further to Gilbert's debug shell keyboard issues: I've been dealing with lots of md upgrade problems lately and non-boot scenarios. Not sure if you're seeing the same thing, but what's worked great for me is boot with kernel args: rdshell rddebug. Don't use the sushell or whatever it was you were mentioning as that forces your login. When the system can't boot due to md / fsck it will drop you in a rdshell (real crap shell) without any pw prompt. From there you can run mdadm commands, and probably fsck, to get your system bootable. In fact, once you get your / fs alive you can mount it to /sysroot and type "exit" and the system will boot as normal! Once in the live system you can run "dracut" (possibly with --force) to create a fixed/bootable rd. Assuming that's your problem. I've used this TONS lately when upgrading linux boxes from non-raid to md raid or small disks (raid) to bigger disks (raid). Any situation where your drive labels/uuids/majors/minors change can fark up your booting. This lets you fix it (without OS reinstall). Had a horrible time just this last week where I had booting md complain that sda3 and sda shared a md superblock and it wouldn't boot. Even with the above tools, I couldn't get it to boot without manual rdshell intervention until I revamped the whole disk so that there was a tiny bit of space at the very end of the disk, so sda had its own tiny area at the end (and I zeroed its superblock). Anyhow, just thought perhaps there may be some overlap in problems and I could save you some headache. Linux: the (nearly) only OS you can always fix and never need to reinstall (upgrade or wipe/install). Love it! (Note to others, this stuff may be RH/Fedora specific as I have no idea if other distros use dracut or provide rdshell.)
