Hello Patrick, I have resubscribed using one of my business addresses (IMAP) instead of address on bellsouth.net (POP) -----Original Message----- From: Patrick O'Callaghan <poc usb ve> Subject: Re: [Evolution] [Fwd: You have been unsubscribed from the evolution-list mailing list] Date: Sat, 30 Jul 2016 23:34:05 +0100 On Sat, 2016-07-30 at 22:54 +0200, Ángel González wrote:On 2016-07-29 at 15:24 +0100, Patrick O'Callaghan wrote:OK, good sleuthing :-)It's tempting to think so, but there are also users with pacbell and bellsouth addresses who have similar problems. I note that both of them route their mail through prodigy.net, if that means anything. pocApparently, prodigy.net email service is actually provided by yahoo; https://en.wikipedia.org/wiki/Prodigy_(online_service)#A_public_company So it is really just yahoo having problems with emails from their own customers that passed through a mailing list.I got the hint by the error message given by the prodigy mailserver when attempting to spoof a yahoo From:Looks like it, however I don't understand why it's only affecting a very small number of users, and only occasionally.<<< 554 5.7.9 Message not accepted for policy reasons. See https://help.yahoo.com/kb/postmaster/SLN7253.html 554 5.0.0 Service unavailableI'm quite sure it is related to their DMARC reject policy (perhaps even marked internally).It asserts that yahoo.com emails will only ever come from yahoo servers, and non-complaint emails shall be *rejected*. This makes complete sense for eg. paypal.com but for a free mail provider like yahoo imho such policy is broken. Precisely because it completely breaks mailing lists: https://en.wikipedia.org/wiki/DMARC#Mailing_lists Also, it should be noted that other providers may also be taking that into account. For instance gmail accepts those DMARC-failing messages, but they are sent to the Spam folder.My address (@usb.ve) is a Google Apps for Education account. I have another Gmail address on several Mailman lists. None of them has ever been affected by this.There are a few options in recent mailman versions for handling this, although none seems specially appealing: https://wiki.list.org/DEV/DMARCI'll consider passing this on to the Gnome admins but it's seems likely they would already know about it. poc _______________________________________________ evolution-list mailing list evolution-list gnome org To change your list options or unsubscribe, visit ... https://mail.gnome.org/mailman/listinfo/evolution-list |
