    Trouble sending email to certain domains. It looks like it is forwarding the local domain name causing reverse lookup to fail to resolve to the correct name. New install of Exchange 2010 RU4, on Server 2008 R2. Currently co-existing with a 2003 exchange instance, but it will be removed eventually. Mailbox, CAS, and HUB roles installed on SERVERA. The old 2003 Exchange box is ServerB.  Mail still routes incoming to the Exchange 2003 box, SERVERB, as the NAT’s have not yet been changed on the router. I am unable to specify a FQDN on the send connector of the Hub Transport under organization configuration, as it is grayed out. Is this specified in AD? What am I missing? Any help is greatly appreciated.

  • Grayed out means its a 2003 connector, not a 2010 one.  which is fine for now.  but this means the problem isnt likely related to the 2010 server since, as Jonas mentioned, 2003 is doing both inbound and outbound.

    I'd update the PTR record just for logic sake.  no reason to involve a domain not part of the mail flow.

    Did you visit www.mxtoolbox.com?

    I see you're using postini.  perhaps do outbound through them as well, to offload the administrative burden of IPs and such to them.

  • Problem solved. I'm not completely sure the PTR had anything to do with it because when I moved a couple mailboxes back they worked just fine. But it is so odd because Exchange14 was sending our through the 2003 box.. Anyways what fixed it was creating a new send connector to point Exchange14 directly to the internet instead of using the SMTP connector on Ex2003. Thanks for your help and time guys..

  • Are you using send as, or anything less than normal email from outlook and MAPI?

    do you have a valid MX record for your domain?  Please visit mxtoolbox and run the supertool.

    Finally, enable protocol logging on your send connector and paste here the relevant lines dealing with a submission to this domain.

  • If you haven't changed anything the mail will route both in and out through the 2003 server

     

    Update us on the thread about the MX info Mike wrote about and the logging

  • No send as, just users sending from their own account.

    I am unable to enable protocol logging, as that box is grayed out as well as the specify FQDN. This is the only send connector I have, and is under the organization level. There are no send connectors under the Server Config,  hub transport. Am I missing where I should enable the logging at?

    The reverse lookup is a little odd to me. Our main domain name is wculife.org, but the reverse is showing wcu1.westerncatholicunion.org. We also own this domain, but it is not the domain associated with our emails. Should this be changed? It has been like this for 6+ years, and has never been an issue until I installed Exchange 2010. Thank you much for your time/help

  • Are you using a 3rd part mailwasher or do you receive the mails directly to the company and in?

    I did a check for your domain agains mxtoolbox.com

    100    wculife.org.s6a1.psmtp.com    64.18.5.10

    64.18.5.10 should point back to wculife.org.s6a1.psmtp.com

    Normally this is done by contacting the ISP, they can help you with this

  • Yes I did visit mxtoolbox, and used the supertool, that is where the paste output came from on the pointer and reverse lookup.

    I'll ask the ISP to update the pointer record.

    Tuesday, August 10, 2010 1:45 PM
  • Yes we are using Postini for antispam. 64.18.5.10 points to Postini.
    Tuesday, August 10, 2010 1:47 PM
  • Ok, give your ISP a call and update us then it's done

  • I contacted the ISP, waiting on a response.

    For the pointer record

    Type    IP Address    Domain Name    TTL
    PTR    216.138.22.51    wcu1.westerncatholicunion.org    4 hrs
    reverse lookup    smtp diag    port scan    blacklist

     

    what does wcu1 refer to? Is that a placeholder or what? I've never seen wcu1 referenced anywhere besides this record.

    **Found out this was an old server before my time here. Not sure why everything worked with the bad pointer record before, and now that the mailboxes are moved to Exchange 2010 and routing through the 2003 box they are failing the reverse lookup.

  • ISP is quick to respond, love it! Here is the response from them

    "

    "We can change this for you to 'wcuserver.wculife.org'.

     

    The existing PTR record was based on an old setup.

     

    Note that the server answers with a ".com" hostname....

     

     

    Connected to wcu1.westerncatholicunion.org (216.138.22.51).

    Escape character is '^]'.

    How can I get the exchange server to respond with the external domain wcuserver.wculife.org instead of the internal wcuserver.wculife.com ?

     

    TY guys so much

  • Does your Exchange send the mail out directly or are they routed through Postini server?

  • Directly. The connector on the 03 box says to use DNS to route to each address space.

    *edit. And there are no routing groups

    When I telnet to SMTP, should it respond with the external domain name?  It is responding with .com, which is our internal.
