Even more amusing is when half your customers are in Gmail, the other half in Exchange, and Gmail and Exchange are having some snit so the emails ain't happening. You call up Microsoft and they want you to reboot (??) or login to some windows account (??), and good luck getting someone from Google on the line. Fear not, for outsourced email saves money, and increases productivity, or anyways something like that, and if you have sufficient faith those big old corporations will fix things, eventually, maybe.
I, for one, welcome our new AOL overlords.
