Greetings to all,
I’m at my wits end. I have a WIN2k3 server that is running Exchange 2K3. We have having a problem with mail going from the exchange server to ANY place else. Inbound email from internet is fine and telnet outbound to a server running pop3 is fine.
There is a firewall between us and the internet but this is for outgoing connections to the internet. It doesn’t matter if its the example domain below, gmail, aol, or ibm… It just doesn’t work.
We are receiving following from smtpdiag…
C:\Documents and Settings\Administrator\Desktop\SmtpDiag>SmtpDiag.exe tearl@l33t
gamesinc.com tearl@cacdhh.org /v
Searching for Exchange external DNS settings.
Computer name is L33T.
VSI 1 has the following external DNS servers:
209.124.35.6
Checking SOA for cacdhh.org.
Checking external DNS servers.
Checking TCP/UDP SOA serial number using DNS server [209.124.35.6].

Checking internal DNS servers.

SOA serial number match: Passed.
Checking local domain records.
Starting TCP and UDP DNS queries for the local domain. This test will try to
validate that DNS is set up correctly for inbound mail. This test can fail for
3 reasons.
1) Local domain is not set up in DNS. Inbound mail cannot be routed to
local mailboxes.
2) Firewall blocks TCP/UDP DNS queries. This will not affect inbound mail,
but will affect outbound mail.
3) Internal DNS is unaware of external DNS settings. This is a valid
configuration for certain topologies.

Both TCP and UDP queries succeeded. Local DNS test passed.
Checking remote domain records.
Starting TCP and UDP DNS queries for the remote domain. This test will try to
validate that DNS is set up correctly for outbound mail. This test can fail for
3 reasons.
1) Firewall blocks TCP/UDP queries which will block outbound mail. Windows
2000/NT Server requires TCP DNS queries. Windows Server 2003 will use UDP
queries first, then fall back to TCP queries.
2) Internal DNS does not know how to query external domains. You must
either use an external DNS server or configure DNS server to query external
domains.
3) Remote domain does not exist. Failure is expected.

Any suggestions would be great!
