Sorry it's taking so long to resolve this. It didn't start at a well-defined time, but "nothing had changed" (really, so far as I can tell) when it became serious, and nothing I can track down yet seems to show any clue to what's happening. It still happens on some other mail arriving here as well. I've by now made dozens of changes, without learning anything about the underlying cause. The examples I've examined appear to be duplicated in the process of transit from ns2 (also primary MX) and gw. One thing I'm trying is dropping ns2 as the primary MX for dragaera.info, so all the mail comes in direct. Perhaps that will at least reduce the incidence. I've completely changed the protocol used to refer mail from ns2 to gw, with no change I can find in duplicates. -- David Dyer-Bennet, <mailto:dd-b at dd-b.net>, <http://www.dd-b.net/dd-b/> RKBA: <http://noguns-nomoney.com/> <http://www.dd-b.net/carry/> Pics: <http://dd-b.lighthunters.net/> <http://www.dd-b.net/dd-b/SnapshotAlbum/> Dragaera/Steven Brust: <http://dragaera.info/>
