[DECtec] [HECnet] Fwd: [H390-MVS] Yahoo DMARC Implementation Breaks Most Mailing Lists

by johnhreinhardt＠yahoo.com

Thanks Greg. I think that pretty much explains why I don't get back copies of my posts. Also why I haven't noticed it until now. Virtually all of the newsgroups/lists I subscribe to are Yahoo groups. HECnet, DECtec and a couple others are not. The Yahoo ones are ones I interact with most. Although I've gotten posts to appear on DECtec sporadically, HECnet has failed 100%. I'm also a member at CCTalk and CCTech and I recently had a post succeed there. Probably, like most things Yahoo, the DMARC policy doesn't work 100% of the time. Well, I was looking around for a new email host anyway that I can use with some of my owned domains. I guess this just forces me to speed the search. Are you any relation to the John R. Levine mentioned? John H. Reinhardt On 4/10/2014 6:46 PM, Gregg Levine wrote: Hello! See below. That was just sent to the H390-MVS list.

While Yahoo is the initiator, it also affects Comcast, AT&T, Rogers, SBCGlobal, and several other ISPs. Internet Engineering Council expert John R. Levine, a specialist in email infrastructure and spam filtering, said, 'Yahoo breaks every mailing list in the world including the IETF's' on the Internet Engineering Task Force (IETF) list. DMARC (Domain-based Message Authentication, Reporting & Conformance) is a two-year-old proposed standard previously discussed on Slashdot that is intended to curb email abuse, including spoofing and phishing. Unfortunately, as implemented by Yahoo, it claims most mailing list users as collateral damage. Messages posted to mailing lists (including listserv, mailman, majordomo, etc) by Yahoo subscribers are blocked when the list forwards them to other Yahoo (and other participating ISPs) subscribers. List members not using Yahoo or its partners are not affected and will receive posts from Yahoo users. Posts from non-Yahoo users are delivered to Yahoo members. So essentially those suffering the most are Yahoo's (and Comcast's, and AT&T's, etc) own customers. The Hacker News has details about why DMARC has this effect on mailing lists. Their best proposed solution is to ban Yahoo email users from mailing lists and encourage them to switch to other ISPs. Unfortunately, it isn't just Yahoo, although they are getting the most attention." -- DECtec mailing list http://dectec.info To unsubscribe from this list see page at: http://dectec.info/mailman/listinfo/dectec_dectec.info

Hello! I've been seeing them. On both places. However Google Mail because how list servers re-write headers insists that your e-mail can not be coming from where it says. I promptly move it from the Spam bucket back to the Inbox. I have that same problem with other lists and mail written by folks from certain banks. ----- Gregg C Levine gregg.drwho8 at gmail.com "This signature fought the Time Wars, time and again."

Ah was that it. I thought the 50 denoted the 2-cpu version, the 00 the single cpu and that the 83xx was the faster version? of the 82xx I always had trouble with this too, but here's the scoop - VAX-8200 - 1x KA820 (T1001-00) CPU VAX-8250 - 1x KA825 (T1001-YA) CPU VAX-8300 - 2x KA820 CPU VAX-8350 - 2x KA825 CPU The model numbers corresponded to the CPU cards (e.g. KA820 -> 8200, KA825 -> 8250) ... The KA825 (T1001-YA) was simply a faster version (6.25MHz vs 5MHz) of the same KA820. Bob

The difference between the 82xx and 83xx is that the 83xx was a 2-cpu SMP system while the 82xx was a single cpu. The 8200/8300 was fairly short-lived before the 8250/8350 came out. John H.
