My friend wrote a parser for Haskell-cafe messages from the mailman archives as suggested. He told that there were a lot of messages that he had to reject because they didnt have a valid In-Reply-To header. i.e., the In-Reply-To header referred to some message that wasnt in the list of messages! Perhaps it was from another month's message! Thanks, Vimal On 11/12/2007, Albert Y. C.
