-------------------------------------------------------Hello,

You should take a look at the internal and external DNS lookup settings to
make sure they don't point to a DNS server that is providing a negative
response for some reason.

A telnet session wouldn't show this error.

-------------------------------------------------------Does running the mail
flow troubleshooter give any more details?

Is this a new connector or an existing one that broke?

http://www.msexchange.org
-------------------------------------------------------Using a exchange
2k7sp1 Send connector to forward email to a smarthost.
i have entered the FQDN of the smarthost in the connector.

when i send email i get a "451 4.4.0 DNS query failed" in the queue
but I can telnet on port 25 from the hub transport to that smarthost
using the fqdn and nslookup from the HT resolves correctly as well.

No auth is being used.



any ideas?


thanks guys
