how to find smtp address on exchange server


  • hello all, I thought this would be an easy find. anyway in a corporate environment. exchange server 2010 has an smtp address? if so where in the configuration will i find it, if not and I have an app that needs the ingoing and outgoing smtp address what else can I use? I kind of understand if it does not have one I can create one in the hub transport and is there an mx record involved? I am the jr I.T. guy tasked with finding out the process on this. thank you for your help.

  • Hi

    If your application just needs to send then you can create a new receive connector for it.  If it needs to send and receive then it will need a mailbox on your Exchange server.  What protocols does the application support MAPI, IMAP, POP3?

  • it says pop3,

    If it just needs to send I create a receive connector, I've been seeing a lot of how too's on that,

    but the app still needs the smtp address? how do I get that or where do I find or create that?

    If it needs to send and receive then I create a mailbox and create a pop3 connector cool stuff :-)

    question how do I find what the mx record is and where it is located?

  • The SMTP address with be the name or ip address of you hub transport server.  If you only have one server with multiple roles then it will be the name or ip address of that server.

  • its an internal address and internal ip, that does not seem right?

    can that be used for the incoming and outgoing smtp address?  I did a nslookup then a set q=mx that gave me something different.

    its something like inatlamail.mycompany.priv

    when I ping it I get an internal ip address

  • Is your application internal and and the same network as your Exchange server - it would use the internal IP to contact the Hub transport server which would then relay either internally or externally if required.

  • ok, I see a hub transport header in exchange 2010, i read that the send and receiver connector should be setup there?

    let me ask this again to be safe, I have a program that is asking for the inbout email pop server, u/n and p/w and the

    outbound e-mail smpt server  u/n and p/w and return address. if I can find this ifno on exchange server 2010, I need to create an smtp send and receive mail connector? and I just create this info to what I want it to be? I read something bout mx record, how do I point the connector to that?

  • HI, you need to allow your application server relay off your CAS servers , here is the link explaining how to configure and test the relay.

    Allow Application relay server relay off Exchange 2010 HTS server.


    good luck

  • this is an internal appliance that can be configured to send email alerts. The appliance is called sensaphone

    Can I still use/try the technique you have in your link does it still apply to my situation?

    Monday, June 18, 2012 8:41 PM
  • Yes, it falls into the same category as an application server.  You don't need to create another send connector, just a receive connector.

  • hello all, I used http://www.mxtoolbox.com/SuperTool.aspx put my companies domain name. and ran a smtp test which gave me my outside smtp address. and ip. I ran a ping test could not ping it from inside, boss said blocked by firewall does that make sense? do you normally block your outside smtp ip address?

    btw the nslookup command gives me the same info as the mxtoolbox but u have to run the nslookup from outside your network to get the outside info, if u do it from inside your network you get inside info.
