Sorry to hear the compatibility has gone downhill. Original versions of the TIFF format only accommodated a single image. New TIFF support multiple pages (as you well know), but ".tif" is pretty much a legacy extension. My guess is that the sender(s) are sending an old or incorrect MIME type in their e-mail, and Snow Leopard is relying on the .tif extension to indicate the file format. Changing the extension to .tiff probably causes Snow Leopard to re-evaluate the content on its merits, at which point the MIME type is replaced with the correct UTI. Of course, that doesn't explain why printing works, or how you can fix your problem. Sorry!
