  • DNS configuration for Exchange 2003

    How do I setup my DNS to receive Internet Email? I can not receive Internet emails. I can send out, but can NOT receive.

    I read the following:
    http://www.petri.com/configure_mx_re...il_traffic.htm
    However, I do not understand where to put everything.
    I have the following local internal DNS setup:
    DNS
    -GBSERVER6 (server)
    --Forward Lookup Zone
    ---greatbay.local
    Name Type Data
    (Same as parent folder) Start Of Authority [38],gbserver6.greatbay.local.
    (Same as parent folder) Name Server gbserver6.greatbay.local.
    (Same as parent folder) Host 192.168.1.41
    gbserver6 Host 192.168.1.41
    mail Mail Exchanger 192.168.1.41
    --Reverse Lookup Zones
    ---192.68.1.x Subnet
    (Same as parent folder) Start Of Authority [1],gbserver6.greatbay.local.
    (Same as parent folder) Name Server gbserver6.greatbay.local.

    How do I setup my DNS to receive Internet Email?
    Any help would be appreciated.

    Re: DNS configuration for Exchange 2003

    To receive emails you need to have:
    -A public IP address
    -a registered domain name
    -publicly accessible DNS information (A, MX, etc)

    Your internal DNS information is not where things need to be configured to receive mail from the Internet.
    From the article you're following:
    In order to properly configure your domain's MX Record you should contact your ISP (Internet Service Provider) or the party responsible for hosting your DNS Domain name. They will ask you for your FQDN (Fully Qualified Domain Name) and IP address of your mail server. Make sure you know them.

    Post back with any questions and let us know how it goes.
    Thanks.

      Re: DNS configuration for Exchange 2003

      To receive emails you need to have:
      -A public IP address
      71.98.252.199

      -a registered domain name
      greatbay.com

      -publicly accessible DNS information (A, MX, etc)
      smtp.greatbay.com

      Where and how do I add this information to my internal local DNS? I need details on how to do this, perhaps pictures.

      I have another mail server (Mail Enable Enterprise) that is working great. However, we are replacing this server with the one I’m building. So I know, the firewall, the NAT, the external domain is okay.

      I can only narrow the problem down to the new exchange server 2003 I’m building. I can’t receive internet email. And the problem must be my DNS configuration in Windows 2000.

        AFAIK you don't need to set up anything on your internal DNS zone.

        It sounds like you have an email service right now but would like to switch to handle it internally. Is that correct?

        How does the mail flow now and how would you like it to flow? (diagram would be nice)

          somewhere in here, you may find the correct place to enter your MX records. You should contact them for more info, assuming that they have control over your nameservers.

          The point is that all that information, has to be publicly available, not on your DNS server at all. Your DNS server is private for your organization.

          see here as well to help you troubleshoot.

            I should also stress that I have made an assumption that greatbay.com is a real domain, if not, then adjust my previous post accordingly.

              Re: DNS configuration for Exchange 2003

              I just switched over the port forwarding to my new Exchange Server 2003. I sent a test email from my Yahoo email account.

              I checked the SMTP log files. Here’s what I got:
              16:45:23 192.168.1.41 RCPT - 550
              16:45:23 192.168.1.41 QUIT - 240
              16:46:01 192.168.1.41 EHLO - 250
              16:46:01 192.168.1.41 MAIL - 250
              16:46:01 192.168.1.41 RCPT - 250
              16:46:01 192.168.1.41 DATA - 250
              16:46:01 192.168.1.41 QUIT - 240
              16:46:03 209.191.88.239 - - 0
              16:46:03 209.191.88.239 EHLO - 0
              16:46:03 209.191.88.239 - - 0
              16:46:03 209.191.88.239 MAIL - 0
              16:46:03 209.191.88.239 - - 0
              16:46:03 209.191.88.239 RCPT - 0
              16:46:03 209.191.88.239 - - 0
              16:46:03 209.191.88.239 DATA - 0
              16:46:03 209.191.88.239 - - 0
              16:46:03 209.191.88.239 - - 0
              16:46:03 209.191.88.239 QUIT - 0
              16:46:03 209.191.88.239 - - 0

              C:\>nslookup 209.191.88.239
              Server: vnsc-pri.sys.gtei.net
              Address: 4.2.2.1
              Name: mta-v7.mail.vip.mud.yahoo.com
              Address: 209.191.88.239

              I see the email hitting the exchange server. But my recipients are NOT getting the emails.
              What does this logfile mean? It seems it just stops.

              P.S.
              I’ll have to switch back the port forwarding back to the old email server so my users will not complain about not getting emails.

              Here's my mail flow diagram: I hope it's the correct format.

                Does have to do with my SMTP access setup?

                  Nice diagram.

                  OK, so the emails are hitting the exchange server.

                  -Do you have message tracking enabled? If so, what does it say about the messages?
                  -Are you getting NDRs for your test emails? If so, what do they say?

                  EDIT - just saw your last post. YES! Change the connection to All except the list below

                          I'm sorry for the mis-understanding. I thought it was an internal local DNS configuration error. Why I could not receive Internet emails. Jeremy pointed out to check the SMTP logs. Then Jeremy pointed out NDR's. That's when I thought I better post my SMTP config settings. This was the only Exchange FORUM where I could add attachments.

                          I posted my problem on four other sites. Since November 9th no one could help.

                          I posted it here. Problem solved in 4 hours.

                          I've been going to PETRI.co.il site for years, for PC, server, and network help. This is one of the best sites I go to for any administration help.

                          Keep up the good work you guys and girls. Now... if only Google would buy you out.

                            I guess what derailed me was
                            -A public IP address
                            71.98.252.199

                            -a registered domain name
                            greatbay.com

                            -publicly accessible DNS information (A, MX, etc)
                            smtp.greatbay.com
                            since those mx records did not match what you posted
                            Regardless, glad to see that your issue is resolved.
