  • Exchange 2010 DNS config

    After some advice, Ive built a Exchange 2010 environment and am requesting assistance on setting up my DNS.

    I have purchased a domain (lets call it mydomain.info) from GoDaddy.

    I have set up the following -

    A record:
    Host - mail
    Points to - my Internet IP

    MX record
    Host - mail
    Points to - mail.mydomain.info

    I have opened up SMTP and SSL ports on my router to forward to my (single server) Exchange 2010 CAS.

    Have I done this correctly? I realise it could take 48 hours for DNS to propogate.

      Thanks

      Mind if I ask two more things?

      First, Ive noticed that emails I send to hosts such as GMail are marked as spam, Im assuming that my email domain is not being identified as a valid source. How can I go about ensuring my mail domain is not treated as spam? Id like to use my 2010 setup as my 'real' email system and wouldnt want my emails blacklisted. Is this something to do with Reverse DNS, if so is it something I need to take up with GoDaddy?

      Secondly, in order for my OWA to become a recognized trusted source for browsers I was thinking about purchasing a SSL certificate (again with GoDaddy). Would this stop the hissy fits that IE8 get into when I (any my other users) get when accessing their OWA? I was looking at the Standard SSL for a single domain, would that be appropriate for activesync or would I need to buy a second SSL?

        You need to buy a SAN certificate. (no wildcard SSL cert if you want to use ISA/TMG in future). the folllowing names should be on it:

        Casservername1.internaldomainname
        Casservername2.internaldomainname
        Casservernamex.internaldomainname
        owa.externaldomainname
        autodiscover.internaldomainname
        autodiscover.externaldomainname

        regards

          make sure you speak to your ISP and ensure that your reverse lookup address is configured the same as your A-name.

          tell them you want the PTR to be mail.yourdomain.info
          they should understand.

          this will help with mail - some domains will reject if the reverse lookup isn't valid

            You don't need autodiscover for the internal domain. Outlook doesn't query that URL.
