  • Send Connector when Edge is introduced

    Hi,

    I am running a simple setup where Mx pointed to Firewall.And then opened Port 25 to exchange 2010 server in the Internal network.Send connector created on this server with * and priority 1.

    Now we are planning to Introduce ET.We test setup a scenrio and synced ADLDS in dummy lab.All seems perfect.I need to know whether how will the routing in this case going to work.

    Correct me whereeve rI am wrong;
    1. Port 25 has to be opened for ET in DMZ on the firewall.
    2. ADLDS will communicate b/w ET and HUB/CAS/Mailbox Server.

    Will these default connector going to send the message to outside as well?
    As there is Conector from Edge to internet with some prioirty of 100.
    Or Send Connector on Hub/CAS (manually created initially created before Edge introduce) going to send the outbound mails?
    Or
    Smart host entry (of ET in DMZ) to be added in Send connector of HUB/CAS to or FQDN is fine.
    How will mail going to flow either way?

    If you are creating an Edge Sync, then you will need to change your Send Connector to use the Edge server as the Source Server.
    You don't put another Exchange server as a smart host unless there is no Edge Sync. Although without an Edge Sync an Edge server is a waste of money.

      Simon,

      Edge-Sync being created.
      It has created two send connector i.e
      Edge Sync-Default-First-Site-Name To Internet
      and
      Edge-Sync-Inbound to Default-First-Site-Name

      With Address space
      Type: smtp
      Address: *
      Cost : 100
      and
      Type : smtp
      Address: --
      Cost : 100
      Respectively

      Also the already exsiting Send Connector on the HUB/CAS/MB Server is also there
      with credential
      Connector Name :To Internet
      Type : SMTP
      Address : *
      Cost : 1

      Here wanted to know how will mail to internet will route?
      Will it will HT/CAS to ET or Directly HT/CAS will route it to outside world?
      I am slightly confused here.

        Outgoing Mail will use the edge server as a smarthost, you can delete your manually created send connector at the internal HT server as well.


        This configuration data will get replicated from the HT server to the Edge server using the edge synchronization process.

          Thanks a ton your answer.
          So all manual send connector has to be removed.So only two automatic send connector will be be created with cost 100.

          What all connector going to changed if we introduce a dedicated spam device like Baracuda,Iron Port or fortimail etc.

            If you are going to use an appliance, why did you bother with an Edge? Unless you are getting your licences for free, you are wasting Exchange licences. Edge requires an Exchange server licence, so makes it a very expensive server in a DMZ, and it isn't one that works too well either.

              Simon,

              I am looking forward to use a dedicated AS device like Barcuda or Ironport not Edge server at all.

              I wanted to know how will the baracuda or ironport will scan inbound or outbound mails.Do I really need to scan outbound mails as well or just from my existing mailserver to send the mails using send connector like smtp * 1. and using dns to route mails.Is there any harm doing that or dedicatley need to send the mail to Barcuda using smart host connector IP in the mail server.


              I am also having one more question;
              Is there any other way if I do not publish my mail server for OWA or POP etc.Means can Baracuda or Ironport placed in DMZ and published can autheticate the roaming users and forward the request to HUB/CAS/MB server?

                In many cases you route your email out through the appliance so that it learns about what you are sending. This can ensure that emails are not blacklisted which shouldn't be. However each appliances are different.

                With regards to OWA, as far as I am aware, appliances like Barracuda are for SMTP traffic only. If you want to put something in front of Exchange you need an ISA/TMG.
