The initial debug advice I got was helpful, so I thought I'd take the next step and add relaying to gmail (back to that in a minute), but apparently I just don't get it still. Rolling back to my previously working setup failed also, this time with a new error: 421. I don't get much help looking for explanations of 421 on the web.

If there isn't, what's the proper way to do so?) -Scott
