Re: Can't connect to Mailserver

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.

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.

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

My ISP changed IP's on us - again - and now we aren't getting

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.
