  • MX Records newby

    Hello,

    For testing purposes I have a SBS 2003 Server R2 SP2. In the Exchange configuration I normally use the pop3 connectors to fetch the mail but I want to test it with the full use of MX Records.

    Therefore I have a question, the MX Record should be configured by the ISP it should contain our Public IP address and servername? According to the explanation by DaniŽl this servername should be the FQDN name. Our servername is server1.domainname.local is this what the ISP should know or may I choose a random name like mail.domainname.com.

    We own a website www.domainname.com which is hosted at the ISP...

    If the MX Record is created by the ISP and port 25 is open and anonymous access is allowed on the virtual smtp connector what else should I have to change or configure on the Exchange SBS Server?

    Then there are some additional things I don't fully understand these are:
    Reverse DSN and how it should be configured
    - PTR?
    - A (host) Records
    - Fallback settings at the ISP

    Could someone schematically explain to me the steps which I have to make to setup a perfect MX Record Exchange scheme? or is there a tutorial (for newbies)?

    Thanks in advance

    MX records are never an IP address. They are a host. The host can be anything that you like your own domain. mail.example.com is a common choice. What the host name is doesn't matter, as long as it resolves. I have used owa.example.com in the past as that was being used for OWA access and resolved correctly.

    You shouldn't need to enable anything in Exchange for SMTP delivery, it should be already set. You just need to open port 25 on your router.

    Reverse DNS/PTR records are for outbound email only, nothing to do with inbound email. If you send email via your ISPs SMTP server as a smart host then you don't need to worry about it.

    I am not a fan of fallback settings at the ISP as I find they cause more problems than they fix. They are also a spam trap and you have to have ways of getting the email from the ISP to your server, which usually means the POP3 connector and its drawbacks.

      Hello Simon,

      Thank you for the clarification.. I've given my ISP the Public IP address on which the server can be reached and a hostname called mail.domainname.com so this should do the trick?

      And for Outbound Mail I still can use Smart Host settings like I always do?

      Can I use MX Records and POP3 Connectors all together? because next to the domain mail (MX Records) I want to collect mail from some private mailboxes at another Mailprovider using the POP3 Connectors...

      Best regards,

      Victor

        You can use MX records and POP3 connectors at the same time if you wish. I normally do during the switch over phase anyway.
