Are emails by default encrypted? From my outlook client (2003) in our 2003 exchange setup if I email out some data to an external mailbox, say my hotmail mailbox, is this traffic encrypted, in any way, or just plain text? And vice versa, from home on a hotmail mailbox into a corporate exchange mailbox, is this encrypted?
How about internal to internal traffic, i.e. from one corporate mailbox to another, does that ever traverse the "outside" or is it always internal traffic?
