At first glance, it looks like a problem on their end. If you were
connecting to one of earthlink.net's mail servers, the logs would indicate
several problems on their end.
However, what you are really dealing here is with the IMail bug (which
appears to be fixed in 7.04) where it would send to the A record if it
couldn't reach the MX records. Specifically, 207.217.120.206 is listed as
an A record for earthlink.net, but isn't listed as one of the MX records
for earthlink.net.
Added with IMail's "no such user" bounce message (without indicating the
error code), it makes the sender of the E-mail think that the recipient no
longer exists.
