As with most big Apple announcements, at least a few features slip through the cracks. Thanks to TUAW reader Brandon Werner, we caught one that answers a long-time complaint of .Mac users and critics: server-side spam filtering. Until today (or at least recently; we've never noticed this before), checking your mail at the .Mac site would subject you to any and all spam you receive, since the webmail didn't filter anything out; Apple leaves that up to Mail (or your other client of choice). Now, finally, .Mac webmail offers this option to filter out junk mail right on the server, giving you at least some sort of a break from the stream of junk you might inevitably encounter. Be sure to check out the support document linked at this option, as it outlines a few steps to take to ensure that your email client and .Mac webmail keep in step regarding the messages that actually get filed into the junk mail folder. This will allow you to review those messages either from the webmail client or your desktop client, making it easy to pick out the few genuine messages that get swept away with the actual garbage.
