Daniel at Red Sweater Blog wrote an interesting post about using Mail’s Smart Folders to create a Recently Viewed Mail Smart Folder — seems like a pretty keen tip to me.

I’m giving it a try, and in addition to his Recently Viewed parameters, I’m also excluding it from a few mail folders that I’m unlikely to refer to as often, such as the folder where “Someone has replied to your topic/blog entry/etc” mail goes, and some mailing list folders.

Depending on how you filter and store email, that might not be necessary — or it might be easier to tell it to only look for Recently Viewed mail in certain folders, as opposed to not in certain folders.
