Dec. WLUG meeting reminder! Topic: DMARC, SPF and DKIM

by Tim Keller

Hey Everybody! We've got a meeting tomorrow! Date & Time: December 13th 2018 @ 7PM Location: WPI Student Center Mid Century Room (rm 331) Presenter: Frank Sweetser Topic: DMARC, SPF and DKIM. This topic came up on the list as a possible reason why some people weren't seeing all the mail on the list and I thought it might be an interesting topic. The good old days of the internet are sadly dead. Now that the Nigerian princes have given up trying to distribute their money, we're instead left with more sophisticated attacks. DMARC, SPF and DKIM are a few of the techniques now being employed to help cut down on spoofed email. As usual refreshments and snacks will be provided and afterwards we'll head off from dinner and keep the conversation going. Thanks, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Keith, I can definitely give you a ride. I just don't remember your address. If you're uncomfortable putting it on the list you can email me directly at turbofx(a)gmail.com Frank is going to give a talk about DMARC, SPF and DKIM. How about we plan your talk for January? Thanks, Tim.

Some people take pride in having the latest. I run an internet host, with name server (by definition), together with smtpd and httpd, on a machine with a Tandy monitor, all bought used. (Ask your grandfather what's a Tandy?)

new/old toy soon? (yet another Gigabyte GA-NNN looming)

by Doug Mildram

Thanks for the support and keeping the list alive. Perhaps too alive (I can rant/ramble!) Are Gigabyte motherboards OK? I've only had one so far. Now dying perhaps. Looking ahead..... since I upgrade "combo style" (all ram and cpu attached/included) I'm gonna look at (days from now) a used motherboard+cpu+ram+beast video+beast fan, hope it fits under my hood, dude speaks well about his retired GIGABYTE GA-870A-UD3 SKT.AM3 AMD870+SB850 4XDDR3-1866, IEEE1394 USB3, SATA3, RAID, ATX plus cpu,ram, and even fan info on this BEAST of a fan, should i be scared? https://www.amazon.com/Noctua-NH-U9B-SE2-CPU-Cooler/dp/B002VT1GZ6 doug> I find it cool that a machine/mb that old, is still way more than I need. I've only got one HD/disk for example. I'll try to buy her a tiny computer NEW someday if my new/old cheap-out fails. I want less power! Good brakes please! Ballpark of $100+ for the combo you CAN still find online if you dare and you get lucky that it really works for you. ...below, tangent about the seller i will meet this weekend. Sounds very smart/honest! I almost got him interested in our meeting. He said: (plus, he's a CS engr) Hello network engineer, me> Engineer too....I also a) use Linux only at home b) used Linux only on that machine, rock solid :) The cpu does not come with embedded gpu : I saved 10$ at the time, too bad now!

Topic of Thursday meeting

> From: "Anderson, Charles R" <cra(a)wpi.edu> > Subject: [WLUG] WLUG meeting this week > > We have a WLUG meeting scheduled for this Thursday at 7pm in the WPI > Campus Center, Mid-Century Room (the location we use most often). > > Subject: [WLUG] Re: December Meeting Reminder! > From: Chuck Anderson via WLUG <wlug(a)lists.wlug.org> > > Maybe we could talk about DMARC, DKIM, and SPF! ****pssst! Frank!*** Why does one message say From: cra(a)wpi.edu, and the other From: wlug(a)lists.wlug.org? (Nervermind, CRA explained that.) I don't want to try to prevent anyone from talking about anything, but I don't have much to say about that. I would have wrote you a letter, but I couldn't spell PHLTT!! If Frank does not have a presentation, I could commit by Thursday to make some slides and bring a laptop. I tested slide-showing a few months ago with the WPI cable in the Mid-century Room and it worked. Here's the catch: My usual ride is unavailable that day. I don't drive and I have not been walking well. I used to walk to WLUG; I fell on the hill. No problem; I got up and went on; it happens. I don't want to be carrying heavy and fragile equipment. I tried to go for a walk this morning, but fell and skinned my knee at the end of my own driveway. If someone could commit to pick me up at my house about 1/2 hour before the meeting I would make sure I was ready enough to fake it. I live about a mile from WPI. Send me mail. I will show you some of what I have been doing, and how I do it. The title of my talk: Love Programs work better than Love Poems Computatational Metaphysics Why and how to write soutce code that can be read Or something else if I thnk of it. Someone said recently that one of the best talks ever was Doug Waud showing TeX printing stuff nobody understood. I thought: "I could do that". I am not a pharmacist, so I will dazzle you with Scheme programs and Algebraic Geometry run through LaTeX. All in living black and white (or glowing green). -- Keith

Yes. If you did not see Tim's announcement of the same, then something is wrong. Which leads me to my proposal, which I will put in another message so that it is not lost at the bottom. -- Keith PS: While I was writing this, two new messages came to me from wlug, one appears to be a copy of Doug Mildram's message dated 2018-12-09 the other a reply to that.

I think stock Linux Mint is still on 4.15.

mailing list issues

by Anderson, Charles R

Some people (including myself) have not been receiving emails sent to the list. I'm guessing that DMARC may be blocking messages from senders' domains that have DMARC set up, so I made a MailMan change to enable DMARC Mitigations. This works by replacing your "From: you(a)wherever.com" with "From: Your Full Name via WLUG <wlug(a)lists.wlug.org>". Your original From: appears in the Reply-To: header. I'm also sending this message to test delivery to a few domains like yahoo.com and gmail.com.
