Hello,
Without involving telnet in any way:
Run tracert domainA from DomainC. This
will show the network path from C to A, Then do the same from DomainB to Domain
A. This will verify the basic network connectivity between the nodes and show
the network routes that are being taken.
You need to establish that basic network
connectivity is working.
No matter the results you need to
determine what the network topology that exists between the two servers. Are
their routers, firewall, NAT devices involved in the network path? Once you
know these things you need to find out what their configuration is.
If you can tracert or ping Domain A from Domain
B then there is likely a firewall between B and A that is blocking.
You should also check that you can connect
from Domain A to Domain A just to confirm that the SMTP server on Domain A is
actually listening.

There are
in different locations but we use same ISP, so we are in same ISP network to
say. What happens is that When you attempt to telnet from Domain C to domain A,
an ISp given IP address is then contacted which redirects the connectin to
Domain A's Mail server. In the case of Domain C to A it works ok, and I can
telnet successfully.
In the
case of Domian B to Domain A, they can not get through, and that is were it
times out trying.
Hope my
explanation is clear
Thanks

Hi,
Start by running tracert to determine the
network paths that are being taken. Start with B to A, then try C to A.
Verify the routes that exist on all the servers with the route command.
Verify that the routes are valid. How do the two domains connect to each other?
Are they at different locations?

This is
driving everyone crazy.
Scenario
so far.
Domain B
can not successfully carry our a Telnet session to Domain A. However domain C
can Telnet to domain A.
Domain B
does not have outbound mail filterting turned on, so that kinda rules out mail
filtering issue.
We still
think that this might be a routing issue with our ISP, but it is so difficult
to get them to see so. Any pointers would be greatly appreciated.

1.
When you do the telnet from Domain B to
A and send message does telnet say it was queued for delivery? Did you using
Exchange message tracking?
2.
If possible; have them disable GFI and
test sending.

3: Yes we currently have domain B's domain whitelisted on the

Thanks! Can you verify
the following?
1.
What SMTP server is reporting the NDR
to domain B users?
2.
From Domain B you tried telnetting to
port 25 to Domain A mail server? Did it go through if not; any errors? Did you
try message tracking it?
3.
Did you try whitelisting and also
checking your junk mail?
4.
What content SPAM filter is Domain B
using now?
5.
You verified that all your MX records
are set up correctly?

Hi James,
Sorry for
the confusing scenario, it so happens that we own both domains, and I am trying
to fix it for both. ok this is the story
Domain A
can send emails to domain B, but domain be can not reply to emails sent from
domain A or create and send new emails. however both domains can send to
external domains including Hotmail, yahoo, and recieve emails ok.
There is
not fixed connector between the sites, but we all use the same ISP. now the
story is that Domain A stopped using our ISP for content and spam filtering and
the story is that ever since that happened the problem came about
Hope my
explaination is clear.
Thanks

Can you go over the
symptoms again? Getting confused J I thought it was a reply only issue below:
When we send a mail to the domain it arrives ok, but users can not
reply to our message. They keep getting the 4.4.7 NDR with message delayed and
then timeout.
Or is it that you cannot send to this particular external domain at
all?

I am not quite sure that is the case here, cos we can recieve from the
other side, but can not send, and we can send and recieve from everyone else.
The only pointer here is that we all share the same ISP. So we suspect they
have done something they are not telling us.
This is the story. The other site chose to stop using our ISP for mial
filtering as this was too expensive and chose to have it in house. Every since
that service was disable, this problem started. I think they might have setup up
some sort of static route between the 2 sites which isnt quite right. but that
is only a guess, as they claim all is well <at> thier end.

before with the reply issue but don't recall a resolution. Let me research.

Hi Guys,
any input
on this would be greatly appreciated. We can telnet the smtp relay box, but
nothing seems to get through. everyone seems to think this is not thier
problem. Somehow we feel it is the ISP's but they are not taking responsibility
for this.
Any Ideas
please

Hi,
Someone
recommended we do the following. Not quite sure this does. Please advice
Turning
off EDNS-0 extended UDP packets in W2k3 server's DNS.
(EDNS0 as
defined in RFC 2671)
Server
2003's DNS server has a new capability, it can handle UDP packets greater than
512 bytes. Unfortunately some firewalls cannot pass these packets so it is
desirable to have the DNS server fall back to TCP in this case as it used to do
in previous versions of NT DNS.
To turn
off the EDNS-0 feature run this from a command prompt:
dnscmd
/Config /EnableEDnsProbes 0
Once you
run this your W2K3 DNS server will never advertise its EDNS capabilities and so
will never receive a UDP packet > 512 bytes.
dnscmd.exe
can be found in the Support Tools.
To install Windows Support Tools
- Insert the Windows
CD into your CD-ROM drive.
- Click No if you are prompted to reinstall
Windows .
- When the Welcome
screen appears, click Perform additional
tasks, and then click Browse
this CD.
- Go to the
\Support\Tools folder.
For complete setup information, refer to the
Readme.asp file available in this folder.
- Double-click suptools.msi.
- Follow the
instructions that appear on your screen.

If your able to receive and send mails
through other domains…still you need to have a look at the below points.
Network connectivity issues you can check
using trace route to the problematic domain.
Find out with remote domain administrator
if your domain has block listed in there Database
Try telnet from your exchange server to
Remote domain (C:\telenet problemdomain.com
25 )

Hi,
Please have a look at the below, it can be
any of the below issue.
1)
Network connectivity issues
2)
You might be blocked by Remote server
3)
Try to telnet 25 to the remote server and see
what the response you can see?
4)
Do you use ISP Smart Host for delivering Emails
or you got own SMTP server?
5)
Finally Check the DNS. ( check FQDN is valid for
SMTP Virtual server)
If the issue will not resolve please
increase the Diagnosis logging for MSExchange Transport.
Cheers!!!

Not quite sure why this is happening. But we can send emails to people

When we send a mail to the domain it arrives ok, but users can not

If anyone can point us in the right direction it would be helpful, cos
