Dear MLS list users... Over this past weekend, the IETF was hit with a flood of forged emails sent to many lists and aliases demanding that money be sent to a "bitcoin wallet" in exchange for the deletion of compromising videos of accountholders' personal activities. Obviously it was just junk spam, but the level was quite high. To mitigate it, we inserted a temporary blocking rule for the phrase "bitcoin wallet" into the global spam system, preventing such email from flowing through, based on the strong match for the spam, and the certain knowledge that the IETF does not write standards for bitcoin wallets. Just now, Sean contacted IETF-ACTION about some missing messages to this list over the weekend. In checking the problem, I noted that earlier messages in this thread said, in part: > HKD logic has also been implemented in Bitcoin wallets for a while now Like winning the lottery, this (I thought) improbable phrase matched our rule and caused any replies quoting this phrase to be discarded by our spam system. In the hope that the attack is over, I've now taken out this rule. If you sent a reply to the above-mentioned thread over the weekend, and don't see it in the list archive here: https://mailarchive.ietf.org/arch/browse/mls/ then please resend your email to the list at this time. It should go through without issue now. I apologize for the inconvenience. Glen -- Glen Barney IT Director AMS (IETF Secretariat)
