Running SBS 2003 Premium, Exchange, ISA 2004, WSUS, 2 NIC's and a
router. DDNS provided by dyndns.org. Dynamic IP provided by ISP.
=============================
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. - xx.xxx.xx.xx [Successful connect: Got a good
response [250 Accepted]] (took 3.485 seconds)
mx2.mailhop.org. - xxx.xx.xxx.xx [Successful connect: Got a good
response [250 Accepted]] (took 3.734 seconds)
mx2.mailhop.org. - xxx.xx.xxx.xx [Successful connect: Got a good
response [250 Accepted]] (took 7.922 seconds)
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.
