I rarely use my professional e-mail address for personal affairs. I expect my employer to peek into them, and rightly so, for it's their infrastructure.

Now, there are some companies out there, that block webmail sites, daamit! Fortunately, there are always ways to poke holes in road blocks such as these...

Somehow I doubt that they're counting small business. Either that or among the local Thai restaurant, paint supply store, and barber shop, there's one of them that hired an employee just to snoop on email. How inefficient!
