It's real simple, either mailman is exiting with a non-zero exit code or it's exiting prior to reading all of the message from the pipe. Both of these are conditions which preline treats as errors. Consequently preline exits in such a way that the delivery is tried later in the hope that the mail admin notices and fixes the problem. You need to find out which of those two conditions are occuring - and it's fundamentally a mailman issue. If mailman is exiting non-zero, why is it doing so? A non-zero exit is a programs way of telling you something is wrong. Listen to it. If mailman is exiting without reading all of the message, why is it doing so? Surely if it hasn't read all of the message then it cannot have safely stored it, yes? > It also executes flawlessly when I take that bit of code out of > preline. Not even a ghost proc or crash. Of course - but that proves nothing. You've told preline to ignore all errors from the child. Put another way, you said process the mail but don't tell me whether it worked or not. If mailman ever gets a genuine error, such as quota full or somesuch you'll never know and the mail will simply disappear. The "solid answer" as you put it, is to find out what mailman is doing and why.
