Product is apparently dead. No updates in almost a year, and no messages from the developer in his Yahoo Groups support area in equally long. Unfortunate as when it was running under a fully-supported version of Mac OS X and FileMaker, eMessage Archiver was quite useful. But there are too many bugs now, particularly under Leopard, for this to be a viable solution any longer and there are no indications that any further development is happening. Anyone looking for a mail backup program should look elsewhere.
