I would think that if majordomo asked for a confirmation response from the bogus send address when an attempt was made to subscribe the address, it would not get a response since the address is bogus. Some mailing lists to which I have subscribed ask for a confirmation from the requestor before activating the subscription.

I am on several mailing lists, and I have never gotten any spam through any of those lists, in thousands of messages. I don't know how onelist stops it, but whatever they do seems to be very effective. Since onelist is free of charge, I wonder if it might not be a good idea to move the extropians lists to This can be done without the current subscribers having to re-subscribe; they can all be re-subscribed by the list owner in one operation.

I would think that a person who uses several addresses habitually could subscribe each of them, but perhaps there is some reason why that would be inconvenient, like getting the same messages at all the addresses.

There is so little spam on this list that it's easy to ignore. Here's hoping things don't get worse.
