Okay, turns out Mailblocks wasn't to blame for all the lost e-mail (though they did experience a service outage at the same time as the responsible party--weird). The culprit is 1&1, my domain host. I signed up for three free years of hosting during their big promotional blitz last year. Unsurprisingly, you get what you pay for. Tech support is virtually non-existent. You have to wade deep into to the help pages just to find a support form, and then it takes days before they reply--if they reply at all. But to my surprise, they actually did admit to having problems with forwarding, hence my lost mail.

My all-time favorite blog? Engadget.com, by a mile. A must-see for any true gearhead!
