Edge Transport Server Fails DNS Query When Emailing to one Specific Domain

This issue occurs for the same domain across three different edge transport servers.
All servers are Windows 2008 STD SP2, Exchange 2007 SP1 U9. Emails are delivered using DNS connector from edge. Emails to this one specific domain would sit in the retry queue with DNS query error until NDR was generated. Connectivity Logging generated the following:
2009-09-01T19:52:23.539Z,08CBEDE9198E2DC3,SMTP,subdomain.domain.com,>,DNS server returned ErrorRetry reported by 208.241.124.200
2009-09-01T19:52:23.539Z,08CBEDE9198E2DC3,SMTP,subdomain.domain.com,-,The DNS query for 'DnsConnectorDelivery':'subdomain.domain.com':'cd771f71-77a3-4aca-b002-86f477816910' failed with error: ErrorRetry
I changed the servers DNS settings to different servers with the same response. Validated that manual MX lookups worked, and that I could telnet to any of the three MX records and deliver mail via telnet.
I did a packet capture and received the following:
12 32.280037 172.28.16.55 208.241.124.200 DNS Standard query AAAA SMTPSERVER.subdomain.domain.com
So what is happening is the Edge servers are only performing IP6 lookups, and throughout the log, only for subdomain.domain.com do they NOT perform a regular IP4 A record lookup. I then went about disabling TCP/IP6 as per this article:
http://technet.microsoft.com/en-us/network/cc987595.aspx
this stated to do the following:
Alternately, from the Windows XP or Windows Server 2003 desktop, click Start , point to Programs , point to Accessories , and then click Command Prompt . At the command prompt, type netsh interface ipv6 uninstall .
To remove the IPv6 protocol for Windows XP with no service packs installed, do the following:
Log on to the computer with a user account that has local administrator privileges.
From the Windows XP desktop, click Start , point to Programs , point to Accessories , and then click Command Prompt .
At the command prompt, type ipv6 uninstall .
Unlike Windows XP and Windows Server 2003, IPv6 in Windows Vista and Windows Server 2008 cannot be uninstalled. However, you can disable IPv6 in Windows Vista and Windows Server 2008 by doing one of the following:
In the Network Connections folder, obtain properties on all of your connections and adapters and clear the check box next to the Internet Protocol version 6 (TCP/IPv6) component in the list under This connection uses the following items .
This method disables IPv6 on your LAN interfaces and connections, but does not disable IPv6 on tunnel interfaces or the IPv6 loopback interface.
Add the following registry value (DWORD type) set to 0xFF:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\DisabledComponents
This method disables IPv6 on all your LAN interfaces, connections, and tunnel interfaces but does not disable the IPv6 loopback interface. You must restart the computer for this registry value to take effect.
I did the above, and still, the Edge Transport servers would only perform AAAA lookups, and messages would sit in the queue.
As temporary workaround, created new send connector with the three available MX hosts as possible smarthosts for subdomain.domain.com, and this allowed email flow.
I've tried disabling the TCPIP6, and still doesnt work. Any suggestions?

Hi Allen and Paul,
we experience problems in receiving mails from senders with this Exchage server problem. When we are aware of the problem, we send them the above mentioned link and ask them to make adjustments. Then afterwards usually mail arrives without any problems.
The problem for us is that it seems as if the problem grows. More and more mail does not arrive on our mailadresses (mine for example is [email protected]) And not all of the senders recieve notifications that mail cannot be delivered. As you can imagine
this situation is unacceptable and damaging our customer relations.
Is there anything WE can do? (apart from sending them the information to make adjustements in their Exchange servers...)
I hope you can help us...
Thanks in advance
Leonard
Hi Leonard,
as stated below we where experiencing the same problem with one of our customers. Seeing that it's a DNS related problem we suggested to the customer to change or add an additional DNS service through i.e. dyndns.com. After adding the current DNS records
to the new DNS service mail started coming in from every customer that had problems.
So for your clients i would suggest a similar solution, it helped over here at least.
Kind regards,
Philipp

Not receiving emails from one specific domain

Hi,
I'm having problems with not receiving emails from one specific domain @youmail.dk. It hasn't been an issue earlier, but I stopped receiving the emails late last year. For all I know this is the only domain there's a problem with - I don't have any problems with any other random domain.
There is no rules or anything like that set up, so I have no idea what the problem could be... There's no "failure to deliver" notification send to the sender either.
It doesn't matter if I check iCloud online, on my MacBook or iPhone...
Can anyone help me?
Nina.

Comcast Security Assurance manages email system security and should be able to help you with this. Call them at 1-888-565-4329 (from http://constantguard.comcast.net/dedicated-support/). They will probably want to know the IP address(es) and/or host name(s) of the sending email server(s).

Sending emails via edge transport server fails

Hello,
I am using Exchange 2013 edge server in my DMZ to send emails, but it refuses to send messages to Internet. Once I create a Internet send connector on my CAS server, mails are easily sent to the Internet. My edge subscription and sync happened successfully.
As edge server did not send any emails to the Internet, I checked the message queue on my CAS servers and I noticed that my messages are in the message queue on my CAS server. Could you please help me sort out my issue? Thanks a lot.
Regards,
Pooriya
Pooriya Aghaalitari

Hi
Can you tell us the last error that you can see in the message queue.
Just run get-edgesynchronization and see the results
What happens if you telnet to edge server fqdn from the cas server on port 25 ?
If nothing helps i would recommend you to remove and recreate the edge subscription file and see the results.

EX2010 Hard Bounce email from one specific domain

Hi
I have exchange 2010 install no edge role as i use a smart host. lately it seems exchange is bouncing mails from a particular domain, i view the logs in smart host and see the remote host as my external IP. The smart host vendor is saying that its my exchange
server which is bouncing the mail but since i have no edge role. i am puzzle why my server would bounce those mails

ah you have ex 2010. ok let me capture the screen shots for you.. but please let me know do you have any SPAM protection installed like forefront/ Mcafee or Symantec etc or its just plain exchange with inbuild security. if inbuilt security then go to ECP
-> server config -> hub transport and there enter the IP address of destination server whose mails are getting bounced.
make sure in organization config.. --> hub transport -->IP allow is enabled.

Exchange 2010 edge transport server, degraded desktop / remote desktop

I have a 2010 edge transport server loaded on windows server 2008 R2 that after about 3 days will no longer allow RDP connections or desktop logons due to a serious performance lag / time out. A reboot clears the performance issue for about another 3 days.
I allowed an RDP connection to stay open for the 3 days and it continues to work however actions like trying to load the task manager, start button, computer or any windows not currently open takes an extremely long time. Task manager and perf mon show very
little processor and memory usage.
Tried the following to resolve:
Replaced hard drives (raid 1)
Replaced server (moved drives from one server to another chassis)
Monitoring iops, memory usage and proc transactions. Nothing shows any unusually high usage.
I tried disabled AV services, log monitoring and backup services both while the issue was happening and as preventative measure before the issue arose.

hi cna you check if by any chance you have bandwidth limitations configured. either on router or on tour switch. i had this kind of issue and it ended with bandwidth issue which was configured wrongly. you said this is happening with RDP. hows the performance
when accesing locally
did you check performance counters and event viewer.. anything there

Edge Transport Attachment stripping based upon an emails Subject line.

I am running Exchange 2010 on-prem with a 2013 Hybrid (including a 2013 Edge Transport server for message handling between on-prem and the o365 tenant) connecting to an o365 tenant. I use EMC's SourceOne for archiving running on-prem. The o365
tenant points to a mailbox on my on-prem Journaling server.
What I am seeing is that when o365 forwards emails as attachments from the cloud back to the on-prem Journaling server it is examining the subject line of the message and making a decision to strip the attachment based upon the very end of the subject line.
Example: A simple text message with a subject line of: "Check out the new web site at www.xyz.com"
The Edge transport server is seeing this as being a ".com" attachment and stripping it off before it gets to the Journaling server. So it does not appear to be looking inside the message to see what it actually is and figure out that it is not
a ".com" file but a simple text message.
I have seen this with other file extension types as well. Such as ".exe" . It is also stripping off ".zip" attachments as well, but I understand that and not sure how to deal with it.
Has anyone else experienced this and how have you dealt with it? Microsoft wants me to take the Edge out of play and go directly to from the cloud to an on-prem Exchange server. But that is not an option as the on-prem servers are not exposed to the internet.
Thanks, Bob

Deploy Exchange 2013 Edge Transport Server for multi-site environment

Hi,
I have a multi-site Exchange 2013 environment. The configurations are as below.
Active Directory Sites and Exchange Servers.
SiteA - EXMB1 & EXCAS1
SiteB - EXMB2 & EXCAS2
SiteC - EXMB3 & EXCAS3
All sites are connected via VPN. (Good speed. No latency issues)
All the three Mailbox Servers are in DAG. Only one mailbox database. All servers running Exchange 2013.
I am planning to deploy Edge Servers in the infrastructure (I am doing it for the first time). Normally, it will be in DMZ.
Now, I can deploy 2 Edge Servers for reliability.
Question.
1. Can I deploy 2 Edge Servers and create subscription to all the mailbox server in 3 different site? Or, is it like one edge server can make subscription to only mailbox servers in one Active Directory Site? I am not sure about this and could not find much
information from TechNet.
One Edge Server can make subscription to all 3 mailbox server in 3 sites. Similarly, I can make the subscriptions in the second edge server as well. Configure 2 external MX records with the same priority so that there will be some load balancing.
Also, in such a case if the mailbox database become active from a different site, I need not make any new changes to the Edge Servers right?
2. If the first way is not correct, I will have to deploy 1 Edge Server each for each of the Active Directory Site. (In DMZ only, not in domain)
Make Edge Subscription to the mailbox server in corresponding site.
Make 1 MX record and point it to the Edge Server which is subscribed to the Mailbox Server from which the Database is Active. The problem is, every time will have to change the DNS record when ever the database copy is activated from a different mailbox
server. And the issues with propagation.. delay..
I am not sure which of the above 2 ways will work. Appreciate suggestions from anyone who have previous experience with similar infrastructure.
Thanks in advance. :)

Hi
One or more Edge Transport servers can be subscribed to a single Active Directory site. However, an Edge Transport server can't be subscribed to more than one Active Directory site. If you have more than one Edge Transport server deployed, each server can be
subscribed to a different Active Directory site. Each Edge Transport server requires an individual Edge Subscription.
A subscribed Edge Transport server is associated with a particular Active Directory site. If more than one Mailbox server exists in the site, any of them can replicate data to the subscribed Edge Transport servers.
I don't think there is a solution to subscribe edge servers for more than 1 site. Edge Servers can be scoped only to one site.

Exchange 2013 Edge Transport install fails

I'm trying to install the Edge Transport for Exchange 2013 but it gets to step 7 of 9:
then give's the following error
Error:
The following error was generated when "$error.Clear();
new-ExchangeServer
" was run: "Value cannot be null.
Parameter name: Cannot get child of ADObjectId: this is a GUID based ADObjectId.".
Then in event viewer I have the following two events.

Error: Error:
The following error was generated when "$error.Clear();

I've rebuilt the server but since it has something to do with the GUID I assumed it wouldn't work but I was grasping at straws and it didn't fix the issue.
I can run the setup again and it does finish but it doesn't show up in the list of servers in the ecp management. I've yet to find a solution on this issue if anyone has a suggestion or two it would be greatly appreciated.

Positioning and role of Edge Transport Server

Good afternoon, all!
I'm working on a new Exchange design and implementation project. I had some research that seemed to indicate that I could have my Edge Transport server in the DMZ to receive Internet mail and to act as a web proxy for the Client Access server residing
in the internal network. However, in my testing I haven't found where that is possible.
Will the Edge Transport server provide that capability or will I need to open a path to the Client Access/Mailbox server? Is there a tradeoff in separating the Client Access server into a separate machine in the DMZ for remote access, that is, if the
Edge Transport server won't supply web proxy services, will I need to make a separate machine for Client Access?
Thanks!
Gregg

Hi Gregg,
Based on my knowledge, Edge Server role handles Internet-facing mail flow and act as an SMTP relay and smart host for Exchange servers in your internal network. We can use Edge server if don't want to expose internal CAS and MBX. We can also
configure Anti-Spam on Edge server to block specific emails.
Unlike other Exchange server roles, the Edge server doesn’t need to be a member of an AD domain, so locating it within a DMZ does not create any difficult firewall configurations.
Confirm that any firewall between your Exchange servers and Edge servers allow port 53 for DNS resolution and port 25 for SMTP traffic.
Thanks

Edge Transport Server Limitations - messages delivered per day?

I'm currently on the hunt for some kind of baseline / benchmark that will indicate how many messages per day (or per second) an Edge Transport server is capable of handling. I feel like this should be in some whitepaper somewhere for when Edge Transport
is designed, so you know how many to deploy, but I can't find it.
I know system specs will be a factor. We have the current hardware in our box:
2 processors (2.67 GHz)
16 GB RAM
64-bit OS (Windows Server 2008 R2 Enterprise)
If anyone has come across any kind of guideline for email delivery limitations of ET, I'd appreciate being pointed to them.
Thanks

The current Exchange servers are much faster and beefier than they were when I worked with Exchange 4 Beta 2 with a customer many years ago. They tried to swamp their Exchange server (dual 90 MHz Pentium server with 128 MB RAM) using six Unix workstations
running Mailstorm against it. They had to stop when their primary Unix systems handling inbound email were overloaded due to how they set up their test. And the Exchange server never skipped a beat.
Another customer situation that may help is that I have seen 10,000 messages in an Exchange 2010 queue (due the smart host they were using for external delivery was offline for maintenance) drop to zero within 15 minutes. I'd suggest that you run some
sort of test of your own to determine how many messages your edge is capable of delivering, but these may give you an indication of the expected capabilities.

Edge Transport Server - Exchange 2013 coexistence Exchange 2007

Hi Exchange-Gurus,
We have one Exchange Org.
sub AD Domain1: A.domain.com (with Exchange 2007 SP3 R10)
sub AD Domain2: B.domain.com (with Exchange 2013 CU6); DMZ contains Exchange Transport Server - Exchange 2013
Is it possible to install within the DMZ of AD Domain1 a Edge Transport Server - Exchange 2013?
Thanks.
Guitarman

Hi Guitar,
Thank you for your question.
Is it possible to install within the DMZ of AD Domain1
an Edge Transport Server - Exchange 2013?
A: Yes, we could create an Exchange 2013 Edge server on the DMZ of AD domain1.
Notice: Before we create an EdgeSync Subscription between an Exchange 2007 Hub Transport server and an Exchange 2013 SP1 Edge Transport server, we need to install Exchange 2007 SP3
Update Rollup 13 or later on the Exchange 2007 Hub Transport server.
We could refer to the following link:
https://technet.microsoft.com/en-us/library/aa996719(v=exchg.150).aspx
If there are any questions regarding this issue, please be free to let me know.
Best Regard,

Error cannot connect to server or DNS name when working with the SRDemo

I receive the error cannot connect to server or Dns name when trying to
display the SRlist.jspx page in the SRDemo. I am using the embedded OC4J server . I tried to using the debugger to trouble shoot the problem but I did not get any information that was useful. The url I am using is http://localhost:8989/SRDemo-UserInterface-context-root/faces/app/SRlist.jspx I also tried using the IP address that didn't work . I really need to get through this demo.

What about using:
http://127.0.0.1:8989/SRDemo-UserInterface-context-root/faces/app/SRlist.jspx
Or disabling any proxy settings your browser might have?

Risk of not having an Edge Transport server

What is the risk of not using an Edge Transport server? Is it worth the extra cost? Environment is Exchange 2010 and ForeFront TMG 2010.

Hi,
if the internal server can handle the load I don't see any problem.
Regarding the CAS server is facing the Internet you should have a firewall in front of it that stopps most of the attacks.
