The gossip malling list uses a somewhat obscure and very limited list server called Enemies of Carlotta. Another fun fact is it runs on a 5 watt NSLU2, which has a grand total of 32 megabytes of memory. That's less memory than the very first hardware iteration of The Mail Archive, which was a 90 megahertz Pentium pumped up with 80 megabytes of SDRAM back in 1998. But I digress. We'll switch to gossip over to Mailman 3 once it is ready.
As for the Archived-At: header, this is great news! You may be the first entity actually using the feature for real, so I'm delighted and thanks for the bug report. We'll take a look and see what is wrong as soon as practical, which is probably this coming weekend. Jeff
