OK. I see that. 66.254.194.29 is my static IP from my ISP. When I 
resolve 'mail.ckent.org', that's what comes up. I certainly don't want 
just anyone sending email to that IP to be able to relay!

This is what confuses me - my Windoze PC has Thunderbird set up to 
access email via 'mail.ckent.org', and it's on my local network, just 
like the embedded gadget and the Linux box hosting 'mail.ckent.org'. Why 
does the PC connect reliably, but the embedded gadget fails reliably?
