I would like to add some additional evidence to this post. At first look I
would say that this persons (account) does not exist at this system. However;
I have this exact same problem with accounts I know to exist, in fact if I
bring up my MSN account and send to the identical address it works, as it did
from Yahoo, Hotmail, Juno and AOL. So I know this part of the error to be
false.

It seems that Exchange is falling back on the most reasonable answer it can
provide even though it is not correct. It's not the first time a software
product has returned a incorrect and misleading error.
My system seems to be very happy delivering messages all over the place. What
I have observed in the past several months, is that on some messages with
complicated addresses the SMTP delivery fails. Many of mine that fail have
addresses like these.

Far more complex that [EMAIL PROTECTED] If I recall (though I
haven't been able to find the Q or other supporting evidence) earlier versions
of the IMC/IMS had some problems with certain characters in the SMTP addresses
they did not support. I wonder if we are seeing some lingering traces of this.
After reading some of the follow up post, yes I have done NSLookups, and Telnet
testing successfully, from my workstation and the Exchange Server. So by
everything I know they should work, but all the same they continue to fail.
Besides how do you explain successful delivery to the identical address from
another mail system?

Subject: Network Error During Host Resolution
Kind ladies and gentlemen of the list. I am sending this message again in
hopes that someone will be able to help me. I'm not intending to spam the
list, just looking for some assistance. I've heard from a few people off
list that they've also experienced similar problems, but none of them have /
had a solution and were hoping that I had found something with yesterday's
inquiry.......
If anyone out there can help, or at least give me another direction to
explore I would greatly appreciate it. (I know about MS PSS and it is my
final option, but I'd rather not go there).
My Exchange Server is v5.5 SP4
Problem is as follows:

-End Quoted Error Message-
I'm getting this error when trying to send to de.durr-usa.com, and have in
the past had this error on a few other addresses, but the message has always
eventually gone through in the past. This time though, I can't get anything
to go through to de.durr-usa.com. Supposedly, we have been able to send to
these recipients in the past, but it's only been in the past two months that
there have been any problems that the end user has complained about... No
changes have been made to our Exchange Server or DNS servers for at least
the past 4-6 months.
I am able to look up de.durr-usa.com using the same DNS server that the
exchange server is using, so it's not that the DNS server can't resolve the
host name... I looked up durr-usa.com's DNS records and there is no MX
record for the sub domain 'de' but there is an A record, so theoretically
the Exchange SMTP service should use the A record in place of the MX record,
correct?
I am at a loss.
Thanks in advance.
