Any help would be greatly appriciated. I have an SBS2k3 server behind a sonicwall tz170. The ports for the services i use are forwarded including port 25,80,443,444,1723, etc... I can access these services using my domain name. i can send mail from one user to another using web interface. I cannot receive mail from external sources like gmail, hotmail, ect...

SmtpDiag reported the following:

D:\AppzFTP\Microsoft\DiagUtilities\SmtpDiag>smtpdiag asrimar@gmail.com aaron@gul
fcoast-networks.com /v

Searching for Exchange external DNS settings.
Computer name is GCN1.
VSI 1 has the following external DNS servers:
There are no external DNS servers configured.

Checking SOA for gulfcoast-networks.com.
Checking external DNS servers.
Checking internal DNS servers.

Checking TCP/UDP SOA serial number using DNS server [xxx.xxx.xxx.xxx]. <--my sbs2003 server
TCP test succeeded.
UDP test succeeded.
Serial number: 2009061613
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.
Checking MX records using TCP: gmail.com.

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.

fixed my own problem

1) properties of default smtp virtual server
2) Access tab --> connection
3) cleared any enteries in computers box, checked 'all except list below'

not sure of security ramifications but everything is working just dandy. hope this helps someone else.

regards,

asrimar
