[cobalt-users] OT: Foregin email addresses

["JK" <thejk@xxxxxxxx>]

If this happened once, I would've forgotten about it. But it happened
again today with a different email address.

First, xxx@xxxxxxxxxxxxxxx I get the following error, and my RaQ
server cannot resolve the domain name to an IP address.

----- The following addresses had permanent fatal errors -----
<xxx@xxxxxxxxxxxxxx>

----- Transcript of session follows -----
550 <xxx@xxxxxxxxxxxxxx>... Host unknown (Name server:
cidintmailsic.infosel.com.mx.pemstar.com.mx.: no data known)

Second, xxx@xxxxxxxxxx I couldn't get the exact error message(sorry),
but tracerouting to the IP address (it does resolve this time) results
in either 1) routing loop error or 2) being routed to a different IP
address altogether.

Since my understanding of DNS system is rather limited, I'm wondering
if someone here can explain how international domain names are
handled, as well as any insight into the problems listed above.
Thanks.
