Are we talking about ethic.thought.org?  (Personally I think it's a bit 
arrogant of you to assume we all remember the details of your network 
from week to week, but I'm a grouch, and other's mileage almost 
certainly varies.)

Is your mail server on ethic.thought.org?  If so, you're probably just 
running into a race condition, given that your *only* nameserver for 
thought.org is also on ethic.  Or at least your only announced 
nameserver.  In other words, your mailserver is quite possibly starting 
up, attempting a dns lookup and timing out, all before your nameserver 
is up and running.

What happens if you restart just your mailserver at this time?

If that doesn't resolve the matter, give us some details about where 
your nameserver and mailserver live, and give us the contents of 
/etc/resolv.conf on the mailserver, and tell us for which e-mail 
addresses e-mail isn't flowing.
