Somebody started forwarding every new cypherpunks message BACK to the mailing list. Each such message would, of course, trigger yet another message back to the list, resulting in a runaway situation. My guess is that it's caused by a bug in a procmail script being run by one of three people at io.com. We're investigating. Meanwhile to break the loop I am manually screening cypherpunks messages, which will result in multi-hour delays before your posting is seen by the list (since I only look at new stuff every few hours). I've yanked the three suspect users, and can probably turn it all back on sometime on Saturday. If you have urgent messages to go out, cc them to me personally and I'll probably notice them sooner. By the way, Hugh and I will probably be upgrading our version of Sendmail within the next few weeks, so you can possibly expect some further funny behaviour while we test it. I hope it isn't nearly as funny as this last meltdown. Don't worry, I didn't really write this message. The NSA had a few glitches in their MITM impersonation of toad.com, and posting this to reassure you that everything is OK. :-) John
