Re: [Alsa-user] This appears to be the problem I am getting with this list - and now other lists - DMARC / DKIM / SPF

I really doubted the claim that they don't pass DMARC since they helped set the standard. Well that is an old article but it looks so much like my problem I figured it must be related . . As an aside, Google is happy with either passing SPF or DKIM. Right. From a spam viewpoint, if you pass SPF then you are authorized to send email from that server. There is a slight chance that the domain got spoofed, and that would make it trivial to spoof the SPF. Well, as I said before, despite passing the above checking site - I get reports like the attached which reports fails more often than not for DKIM less so for SPF . . DKIM is another story. It involves public and private keys. For postfix to sign the message with DKIM, you need the private key on the server. The public key is in the DNS so that links it to the domain. So if you own the domain and the private key, you must be legit. Mind you I have simplified DKIM slightly since it isn't worth me spewing a half dozen more paragraphs. See previous response. Try your account with the dkimvalidator: https://dkimvalidator.com/ I did when I had set up this stuff originally (as I said above - everything passed OK then and still does now) - something has recently changed - I am getting dozens of stupid Yahoo messages every time I mail to this list now . . The website creates an email address. You send a message to that email address. Don't leave the subject line or message block blank if you want a valid spam assassination score. Wait a minute or two, then click on the check results box. The output is a bit wordly, but you will see verification for spf and dkim. This is the website I use when setting up email servers. Yes, I had forgotten that I had also used it originally. Technically I have only proved SPF and DKIM work. That should be all that a mailing list requires. Apparently not anymore . . DMARC is a bit more complicated to explain, but it isn't worth talking about unless you fail SPF or DKIM. The email system administrator in theory processes reports from other email servers in order to see if any accounts on their server have been spoofed. I say in theory because there is no way to tell if the administrator reads the DMARC reports. Anyway, now that this problem appears to be greater than this list - I should pursue problem-solving in a more appropriate place! Thanks. On the bright side, I have had no ALSA problems in my latest opensuse upgrade! Great! - although am a Fedora person myself . . Regards, Phil.

To post to the 'FreeBSD questions' list I used a rocketmail = yahoo address. I had no 'mailman 2' bounce score, nothing odd happened, excepted that my posts had the header 'From: Ralf Mardorf via freebsd-questions' showing the mailing list address. I migrated to a 'riseup.net' address for this list and now the header is 'From: Ralf Mardorf' showing my address. On the 'claws-mail list', also a 'mailman 2' list, I'm using an original yahoo address, on this list it's the same, no bounces, just my posts have a 'From: ... via ..." header, with the mailing list address instead of mine. Some time ago mails sent to this list didn't came through to myself (while they came through the list), but even this issue doesn't exist anymore. ___ Alsa-user mailing list Alsa-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/alsa-user
