A while back I had problems because of some bad routing tables. Your old
ISP couldn't send traffic to my box. Then after postgresql.org moved,
I could reach that server, but it appeared that the old dns cache was
still being used and my email was rejected because it couldn't get
a records for my domain name. During this period I could send messages
using a domain literal instead of my normal domain name. The machine
that sends out list mail was also able to use my domain name for the
whole time. (I subscribed to a couple of the lists before an IP change moved
me to the block with the routing issue.)
