For a mail in teh postedAuctions DB to be considered a match to a failed auction message we only look at a small time window Approx 20 min. Any postings that occured before or after this window are not considered. This however seems to be too narrow for the mail system since patch 3.1, leading to failed auctions never recording. We need to expand this window, we use teh uniqueID where possible so we already filter down teh possibilitys, so expansion of eth time window should not effect accuracy to badly.
