[opensuse-project] opensuse mail redirection problem

Hi,
Two people (one an Alpine developer) have complained to me that they can
not send email to me on my opensuse.org alias, because it gets bounced to
them with this message from from a suse.de server:

It looks like the Telefonica host rejects due to a failing SPF check. My guess is that the sender's SPF record does not include the opensuse forwarding host. (obviously). Forwarding of mails is a typical problem with SPF. Usually the forwarding server is advised to implement SRS. -- Per Jessen, Zürich (7.9°C) http://www.dns24.ch/ - free dynamic DNS, made in Switzerland. -- To unsubscribe, e-mail: opensuse-project+unsubscribe@opensuse.org To contact the owner, email: opensuse-project+owner@opensuse.org
Issues with any opensuse.org infrastructure are probably best reported
to the admin@opensuse.org ticketing system, rather than here where
they might not get the attention of anyone who's able to help

Agree. Anyway, we've looked at this issue before - http://osdir.com/ml/linux.suse.opensuse.project/2008-08/msg00005.html Solutions such as https://github.com/roehling/postsrsd might be worth a closer look. -- Per Jessen, Zürich (7.9°C) http://www.hostsuisse.com/ - virtual servers, made in Switzerland. -- To unsubscribe, e-mail: opensuse-project+unsubscribe@opensuse.org To contact the owner, email: opensuse-project+owner@opensuse.org

That's what I'm starting to think. My ISP has probably switched to a strict SPF check, and that the sender ISP requests hard failure, no softfail. In that case, there is nothing that opensuse.org can do. I found in google two ways to check it: nslookup -q=txt gmx.com dig gmx.com txt host localhost and I get: ;; ANSWER SECTION: gmx.com. 83796 IN TXT "v=spf1 ip4:213.165.64.0/23 ip4:74.208.5.64/26 ip4:74.208.122.0/26 ip4:212.227.126.128/25 ip4:212.227.15.0/24 ip4:212.227.17.0/27 ip4:74.208.4.192/26 ip4:82.165.159.0/24 ip4:50.22.171.0/28 -all" gmx.com. 83796 IN TXT "google-site-verification=YxvYPeuavgDRQDYTX-3dSD3JNMsDn5yO7loiNot-h0Q" And looking at the wikipedia: http://en.wikipedia.org/wiki/Sender_Policy_Framework#Implementation ALL Matches always; used for a default result like -all for all IPs not matched by prior mechanisms. - - (minus) for FAIL, the mail should be rejected (see below). My reading is that the sender ISP requests hard fail for IPs not in that list, and my ISP complies. opensuse.org triggers the failure, because redirection breaks SPF, so there is nothing to tell the administrators here because there is nothing they can do Am I reading it right, or am I mistaken? The only thing they can do is create something else instead of a redirector, like a real mail service. For instance, ieee.org had a redirector service, and they switched about a year ago to google services with real email instead, which avoids this problem. And that would be indeed a matter for this mail list, I believe. :-? - -- Cheers / Saludos, Carlos E. R.

There is, see SRS.

Right.

They could install/apply SRS. For openSUSE, I think it would be quite a reasonable thing to do.
The only thing they can do is create something else instead of a redirector, like a real mail service. For instance, ieee.org had a redirector service, and they switched about a year ago to google services with real email instead, which avoids this problem.
Only if you use the google service. I just have my mail forwarded. I think Richard Brown was correct, it's a matter for whoever looks after the openSUSE.org redirection service. Maybe admin@opensuse.org. -- Per Jessen, Zürich (7.9°C) http://www.dns24.ch/ - free dynamic DNS, made in Switzerland. -- To unsubscribe, e-mail: opensuse-project+unsubscribe@opensuse.org To contact the owner, email: opensuse-project+owner@opensuse.org

Ah. I'll have a look.

Ok, then. - -- Cheers / Saludos, Carlos E. R.
