OK, though I'm unclear why a mail client would be rewriting the line
(as opposed to just copying it around).

I was imagining a scenario where someone hit reply to a corrupted message,
generating a mail to cctalk but also a copy to General at classiccmp.org, which
maybe somehow eventually got found and forwarded back to the list.

I'm not getting as many duplicates as I'd expect if every moderator
approved cctalk message came back via cctech.  (Though I did recently
get the whole PDP-8/S thread again.)
