Well, http://www.libsrs2.org/download.html states "testing" which

Yeah - the patch is for postfix 2.1.4 though, and I feel pretty certain
I looked into using it at least 18 months ago. I don't think there's
_any_ testing going on.

Anyway, why is this really a problem for opensuse.org
addresses? "opensuse.org" does not have an SPF record/entry, so no
provider should refuse reception of emails from @opensuse.org.


I think (assume) the problem is more on reception @opensuse.org:
user@xxxxxxxxxxx sends a mail to user2@xxxxxxxxxxxx

user2@xxxxxxxxxxxx is configured to forward a the mail to
user2@xxxxxxxxxxx

domain1.com is exporting SPF records, domain2.com is verifying on SPF
records.

thus:
MX of domain2.com gets a mail from user@xxxxxxxxxxx, transmitted from
the smtp server opensuse.org

if domain1.com is strict (so no -All in the SPF), domain2.com will deny
reception of that mail.
