Anyone else run their own secure linux mail server and set it up with the Touchpad? I've installed all certificates on the device, Doctored my device, and double checked that every input setting is correct, rebooted, etc etc etc. All I get when trying to set up my email is "Unable to sign in". Other email accounts, except for having to change my gmail password, work fine.

I have never had any problems on any other of my dozens of devices with using this email account.
