I assure you that I've spent a really quite remarkable percentage of my life recently examining the qmail logs, and then the things that write them. There is no sign anywhere in any log I've examined of the cause of this problem. The duplicate messages show transiting the system, but there's no indication of any problem in any of those transits, and they don't differ in any way from messages trnasiting the system that do *not* duplicate. -- 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/>
