SuSEs mailinglists are running amok. I guess all subscribers have noticed by now. The problem is still not solved, though.
Some more informatin from Roman Drahtmüller:
it looks like somebody at savoixmagazine.com has put a few mailing lists from SuSE (like for example the security main contact address firstname.lastname@example.org through which I received the email) to their distribution list. Headers are cut at LatestIssue@savoixmagazine.com but remaining content is not changed. Forwarding happens through envelope-rewriting/requeueing.
In the meanwhile, I try to remove that address from suse mailing lists. Apart from the postmaster at apollohosting.com, there is not much that I can do against this spam. If it continues, I will try to reach Apollo Hosting later today.
