It wasn't a DNS or addressing problem.

The problem was a slow Earthlink mail server:

It looks like you submitted the message to
onempop-canada.atl.sa.earthlink.net at 18:23.
onempop-canada.atl.sa.earthlink.net gave it to
fall-pradero.atl.sa.earthlink.net about 13 seconds later,
but fall-pradero.atl.sa.earthlink.net sat on it for about
an hour and forty minutes before passing it on to ns01.ckts.info.

Big mail servers do this when they're heavily loaded (or poorly
configured, or both)
