I should add some more info to aid you (or anyone) in figuring this out).

External NIC is at 192.168.1.10; router is at 192.168.1.1, internal NIC
is at 192.168.16.2.
External NIC is connected to the router, router to the satellite modem,
internal NIC to a switch/hub.
SMTP Virtual Server IP set to "All Unassigned". Access >Authentication
set to all 3 main checkboxes checked. Relay restrictions allowed only for
192.168.16.2, 127.0.0.1, and 192.168.1.10.
FQDN set to whoopingcrane.org. Smart Host to outbound.mailhop.org. (Got
this service from dyndns.org so emails won't look like it comes from a
spammer.) Outbouind security set to Anonymous.
SMTP Connector forwards all email through outbound.mailhop.org, wqith
Default SMTP Virtual Server as the local bridgehead. On the Advanced tab
> Outbound Security, I have it set to Basic and have my login and
passwword for dyndns.org in the user section. TLS is also checked. (All
per the instructions at dyndns.org.)
In Global Settings > Message Delivery > General > Add, the IP listed is
192.168.16.2

Running SBS 2003 Premium, Exchange, ISA 2004, WSUS, 2 NIC's and a

=============================
My ISP changed IP's on us - again - and now we aren't getting inbound
email. I ran a test on dnsreport.com and got the following:

mail.whoopingcrane.org. - xx.xx.xxx.xxx [Could not connect: Could
not receive data: Winsock error #10054.]

mx2.mailhop.org. - xxx.xx.xxx.xx [Successful connect: Got a good

mx2.mailhop.org. - xxx.xx.xxx.xx [Successful connect: Got a good
response [250 Accepted]] (took 3.234 seconds)
mx2.mailhop.org. - xxx.xx.xxx.xx [Successful connect: Got a good
response [250 Accepted]] (took 7.532 seconds)
mx2.mailhop.org. - xx.xxx.xx.xx [Successful connect: Got a good
response [250 Accepted]] (took 11.93 seconds)I've run CEICW a couple
of times - no change. Verified settings in ESM, all good. What am I
missing?

This has nothing to do with your internal network - don't rerun the
CEICW for something like this. What did you change therein? You do have
a router, which should be handling the public side of things....

How is mail.whoopingcrane.org being updated with the correct public IP?
I can see that Dyndns is authoritative for your whoopingcrane.org
domain, but how are you updating it - the dyndns client? Another client?
Don't do this in your router/firewall's 'dynamic DNS' settings - use
client software that runs as a Windows service on your SBS box.

Currently, mail.whoopingcrane.org is pointing at 70.41.130.208, and your
Exchange server isn't answering telnet requests on port 25. Something
is, but it isn't Exchange.. If that isn't your current public IP, as
listed at www.whatismyip.com, that's the problem right there - it isn't
being updated properly.
