  • Question

  • Hello,

    I have a newly installed Exchange 2013 working just dandy, except that it cannot relay mail for two particular domains. 

    Problem domain # 1 gives me an NDR:

    primary target IP address: «Failed to connect. Winsock error code: 10061,
    Win32 error code: 10061.» Attempted failover to alternate host, but that
    did not succeed. Either there are no alternate hosts, or delivery failed to all
    alternate hosts. The last endpoint attempted was 72.52.10.14:25′

    Problem domain # 2 gives me a useless NDR:

    Remote Server returned ‘550 4.4.7 QUEUE.Expired; message expired'<u5:p></u5:p>

    Tracking messages to both domains I get a common error:

    Eastern Time (US & Canada) and generated the error ‘[{LRT=};{LED=};{FQDN=};{IP=}]’.

    Here’s what I have done so far:

    I can telnet to both problem domains on port 25 and get a 220
    DNS resolves both mail server FQDN’s to the correct IP
    Using NSLOOKUP I can see MX records for both domains
    I have verified EDNS using OARC’s site

    Currently I am stumped. Any suggestions or help would be greatly appreciated.

  • Hi ,

    Is this issue is constantly existing on your side or this is the first time you are facing this issue?

    Both the NDR will occur if there is a reachability problem between your smart host and the destination mail server.

    To segregate this issue just do the following.

    1.Instead of allowing the smarthost to do the dns lookup for those domains by using your dns servers.We make use of the etc host file on the smarthost by manually putting the host A records for those problematic domains.

    Please reply me if anything is unclear.

    Thanks & Regards S.Nithyanandham

  • Hi ,

    we can enable the protocol logging on the send connectors and check the error occurred on the logs during the communication from your smart host to the server in the destination domain.

    Most importantly we will face this error message only when the destination server in not available on the particular time when your smart host tries to connect it. 

    Thanks & Regards S.Nithyanandham

  • After some further investigation, I found that one DNS server had a forwarder to the local IP address of another internal DNS server, probably left over and taken from the NIC settings when I joined the secondary DC to the domain a few weeks
    ago.

    I change the DNS server’s NIC properties DNS settings to 127.0.0.1 and deleted the internal forwarder and email to the problem domain is working now.

Having trouble with a fresh install of Exchange 2013 on 2012 R2.

Exchange is installed and all the DNS and autodiscover etc seems to be working fine, as I can open outlook on a domain joined PC and it auto configures etc all good.

When I try to send an email to an external address, it sits in the outbox for ages…. then hours later goes. then it seems to free up and i can send as many emails as I want to the external address.

If i try to send an email to myself or any other internal address, it goes nowhere… it goes into sent items but never comes back into my inbox.

Any tips would be greatly appreciated… after many hours of googling I am stuck.

    Hi James,

    What is your outlook anywhere settings? How do you have the security on this set? I recently installed exchange server 2013 and found that a lot of what should be default settings, were not default settings. 

    Another thing to check is your queue messages. But it sounds more like the connection between outlook and the server which is having the issue seeing that they are stuck in the outbox. 

    Another thing to note that if this is exchange server with no SPs applied, there could be a bug causing the issue. I had major issues with users who had shared mailboxes or had another user mailbox open, whereby the emails sat in the outbox for hours before being sent.

    Or it simply could be your DNS records are incorrect. I hope you get it sorted. Mail servers are fickle beasts.

    Mail flow from EX2010 to EX2016

    I’m in the process of migrating from Ex2010 to EX2016, but I’m having problems when a mailbox on EX2010 tries to send an email to one on EX2016. The reverse order works fine, EX2016 can send to EX2010 though. The message leaves the EX2010 server, and I can confirm that EX2016 receives it correctly using the SmtpReceive logs so there is no TLS issue that I’m aware of, but then the message ends up in the «SMTP Deliver to mailbox» queue (next hop domain = db01), with the following error:

    ——————————————————-

    Last Error: 421 4.4.2 Connection dropped due to SocketError

    Queue ID: EX201619

    Recipients: tctest@mydomain.com;2;3;[{LED=421 4.4.2 Connection dropped due to SocketError};{MSG=};{FQDN=};{IP=};{LRT=}];0;CN=DB01,CN=Databases,CN=Exchange Administrative Group (FYDIBOHF23SPDLT),CN=Administrative Groups,CN=xxx,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=xxx,DC=xxx,DC=xxx,DC=xxx;0

    ——————————————————-

    Any advice on what might be the cause of this, please?
