Hi,
Itamar, by the proxy of Brian, did asked me to look on the bounce iss= ue we have on the users lists. So after a few hours of careful log readi= ng, here is my finding.
The bounce situation ---------------------
We (ml admin) get on a regular basis people who get unsubscribed and message about bounce. People being unsubscribed automatically is bad(tm), and bounces are annoying.=20
Investigation -------------
A first look show that our mails are bounced as they are marked as sp= am by Google. Google doc on the matter do not give much, some people poi= nt to using dkim, spf, etc. But spf is not for us, but for the sender, a= nd dkim is not ml friendly, afaik, and requires upstream support if I understood well.
Not all mails are bounced, which is good. That mean the ip is not problematic.=20
So I took a few hours to look on every bounce and roughly, there is 2 groups.
Group 1 --------
First group is that all mail from the same poster on the users list h= ave bounced at Google. Out of the 16 mail he sent, 16 have been rejected = by Google. I have no idea why, I suspect the spf policy, but it did look= ed ok. None of the mail of answer had a issue, so that's likely not a content problem. =20
However, the ip address of the sender is in the SORBS blacklist, so that's likely what trigger Google spam filter.
Not much we can do, besides contacting him, which I will do.
Group 2 -------- Roughly, that's mail in this thread : http://lists.ovirt.org/pipermail/users/2015-January/030494.html
and the mails from Sandro : http://lists.ovirt.org/pipermail/users/2015-January/030420.html http://lists.ovirt.org/pipermail/users/2015-January/030423.html
Common point, use of goo.gl and ur1.ca. It turn out that both domain = are flagged as URI spam, since that's used by spammer to hide their link.= So I suspect that Gmail started to "learn" about them as spam, as the re= st of the world did : http://multirbl.valli.org/lookup/ur1.ca.html http://multirbl.valli.org/lookup/goo.gl.html
Again, not much we can do, besides asking to people to not use these services ( which is not gonna work I think ).
I may try to use bit.ly red.ht instead of goo.gl. Can we provide our own url shortener on ovirt.org? That should avoid b= lacklisting. =20 I do not think bit.ly is gonna change much. It is likely abused for the same reason by the same people. And the url are too complicated to be sent sometime, so we cannot just avoid them at all. =20 I also pondered about adding a url shortener on ovirt.org. Besides the load on admin team it create, I think it would have the same issue as
Le vendredi 16 janvier 2015 =C3=A0 08:23 +0100, Sandro Bonazzola a =C3= =A9crit : the others after some time, and so we would need to add some authentication, which start to make thing a bit complicated.=20 =20 Not sure if authentication will work as expected, but this one seems quit= e simple to configure and deploy: https://github.com/mrtazz/katana
Not that keen on adding it on the infra, but could work for openshift maybe ? --=20 Michael Scherer Open Source and Standards, Sysadmin --=-VS26s3x5hcIfdPLzbvFe Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQIcBAABAgAGBQJUuNAWAAoJEE89Wa+PrSK97AIP/iFyauFXbQYI+uNaF8p4tw3A 4FY/2vc0Lp9CtscFIVK3fvYTWPb1WCIQAMEtnrKSPewkZ56HZBDn5seAOvcoD+kH u3zBCfNboR/yU5SIT284czYPbfjizm0UgIgIoROjkWHfPR5r0paZBHiJ6d3gd7k/ B5YhpgtHy5DMoKBuXDHVgjMIPXNiQavfLRvaLGWERa0eHK0BtclBTqD2OanMJEIh Cfulu2oUJfyWRiOXu90ItZBc+7zQ96LfbRS/y4Is526T4beV71Xs8A5PT9gSxsBE zv7wQJzdliq62+4xNYkcDKghcf7Wu114icyVp69jRnzQhbNFJu7QzO/nj3umdgaU 88ArrL+ON02Lcqn9rxFuJ+UB8nX2c/suXg7lIYIta89IKFXFEqIFXFczK38xz5ME 6G6NEZzV94t8t2BKLdZemT/kH2r+t+ITR5meb6pCYDyE/JMIAzXCKrhvl7izwxp+ pN1axehtr2I6r7TBew5NaNts1F+H9Re6CCS2dHULKlsizb9sELJk7yLi4+ovd4XD kqqtMYQwgLj1v3as1vh1jsMiq+0t5H7/VGFwqP42MDwGl2/brBqAcqnd93YcNUpk +p+xjCTolYCq6W9nXbV3QIsCb1s+8+JynepR4sAm9lhf0C7kei7SzNqME64A/pKj EOakMnpZXWwv8+9bQvvf =ijrJ -----END PGP SIGNATURE----- --=-VS26s3x5hcIfdPLzbvFe--
