Turned out the hotel was transparently intercepting smtp traffic and funnelling it through their own relays. T-Bird's CRAM-MD5 auth was failing because their relays didn't support it. Try telnetting to what you think is your smtp server and see if your own banner comes up or something else -- that's how I discovered what was happening. It was a little unnerving until I figured it out. Out of spite I just tunnelled everything through ssh. How dare they f**k with my mail! EB
