Just got in to work and found a bunch of emails when I opened
Outlook. It seems they started flowing in about 7 PM CDT yesterday.
Haven't had a chance yet to dig into the server and find out why. I'm glad
it's working, but it worries me not knowing why it's back up
with no changes by me after 4 PM CDT.

I'm wondering whether your update client hadn't done its work properly. Did
you compare the IP reported by www.whatismyip.com to what you got when you
tried to ping mail.whoopingcrane.org, when this was *not* working?

Hi Mike... are things working now ?

Email got returned at 01.53 so indicates email collection and telnet
IP on port 25 responds with your exchange server.

Are you sure your ports are open ?

1. When I telnet to port 25 I should get a response from your
exchange server (assuming not pop3)... this fails

2. Scanned your Ip... (sorry but trying to help...lol) it doesn't
show any ports open, not even 3389, how did previous help TS
in...lol 3. I sent a test email to your ip to generate an NDR from your
exchange (confirm IP of server) an hour ago, no response as yet..

Goto www.grc.com and choose shields up and test individual ports,
25, 443, 444, 4125 and 3389. Assuming opened ports for RWW, SMTP
and TS. "Mike Webb" <Mike_Webb@xxxxxxxxxxxxxxxxx> wrote in message

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

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.
