I usually check these complaints carefully and I never found anything. > > A few weeks ago many of you will remember an onslaught of duplicate messages which I ultimately tracked down to Ngoi Sing Teck in Myanmar who was (probably without knowing it) looping hundreds of messages from his inbox back to the list. I added a mechanism to the LUG software that blocked such messages, and I haven't had any complaints about duplicated email since. > > I installed this loopback-preventer on July 23. Since then there have been dozens of people looping back a message or two. The guilty software has always been Microsoft Outlook (never Outlook Express). I never would have discovered the problem had it not been for the avalanche of looped-back messages from Myanmar, but there wasn't another avalanche. > > Today michaela@kirk.ca looped back 190 messages to the LUG, which would have been delivered to all of you had it not been for the prevention software. > > Now I find myself wondering two things: > > 1) What madness in Microsoft Outlook causes it to do this, and > 2) How long has this been going on? > > You probably find yourself wondering one thing: > > 1) Brian, why don't you shut up and go take some pictures. >
