Domain mapping and subdomains

  • Unknown's avatar

    I own a domain (myexampledomain.com) at an external registrar, which I’ve mapped to a wordpress.com blog (myexampledomain.wordpress.com. I have a mail address at Google Apps ( (email visible only to moderators and staff), using the procedure here: http://support.wordpress.com/domain-mapping/custom-email/

    Now here is my issue: I want to access my webmail at mail.myexampledomain.com, i.e. a subdomain of myexampledomain.com.

    As I’ve understood, I can only set up subdomains at my external registrar, as wordpress.com doesn’t allow custom URLs. Hence, I need an IP address for myexampledomain.wordpress.com</strong so I can set up an A-record routing myexampledomain.com to myexampledomain.wordpress.com.

    Does wordpress.com offer this functionality? If not, can it be solved in any other way? Or is it impossible to use subdomains when the main domain (i.e. http://myexampledomain.com) is mapped to a wordpress.com blog?

    wordpress.com blogs can be mapped to either the main domain or to a subdomain of the main domain. You can have one wordpress.com blog mapped to the main domain and as many others as you want mapped to as many subdomains as you want. Normally that is done by setting the CNAME at your registrar, e.g. CNAME blogname.domain.com pointing to blogname.wordpress.com. That would make blogname.wordpress.com the blogname subdomain of domain.com.

    Whether you can access your mail at mail.domain.com or not has nothing to do with the subdomain setup at wordpress.com. You need a mail hosting service to do that.

    Thanks for your reply.

    If I understand you correctly, I can map http://domain.com (and, of course, http://www.domain.com) to http://blogname.wordpress.com using CNAME? As you can see, I do not want a subdomain of domain.com mapped to the wordpress.com blog. In my registrar admin settings, I am not allowed to add a CNAME for domain.com because the zone file already contains NS records for domain.com (i.e. the name servers). Adding CNAME records for subdomains of domain.com is no problem, but this is not what I want to do.

    My email is hosted at Google Apps. I have no problems with email hosting, but I need the subdomain http://mail.domain.com mapped to google apps, so I can easily access my webmail. As custom URLs are not supported using domain mapping at wordpress.com, I need to configure the subdomain at my registrar.

    If I understand you correctly then, basically this is not a wordpress.com question but a mail server setup question.

    I think I see now. The answer to your initial question is this:
    If you want to have a mail.domain.com for access to the mail for your domain, you need to find a host for your domain that offers such services. wordpress.com does not offer this.

    As I’m not fluent in DNS terminology, maybe I’m not explaining myself correctly :-)

    My problem is that if I map domain.com to blogname.wordpress.com using wordpress name servers, I am not able to create subdomains with CNAME records. This is because my registrar requires that I use their own name servers if I want to set up custom DNS records, and because wordpress.com doesn’t offer custom DNS records at all.

    If I use my registrar’s own name servers, setting up subdomains with CNAME is no problem. But then I can’t map domain.com to blogname.wordpress.com. This would be possible if I could get an IP address for blogname.wordpress.com, then I could use an A record in the zone file. I haven’t found out whether this is possible.

    If you want to have a mail.domain.com for access to the mail for your domain, you need to find a host for your domain that offers such services. wordpress.com does not offer this.

    Yes, as I said in my initial post, I can only set up subdomains at an external registrar. Hope I made myself clearer now :-)

    Regarding the IP address, my suggestion is to contact Support http://support.wordpress.com/contact/

    The registrar name server thing is interesting, because that has never happened to me with my registrars over the years, but every registrar is a little bit different. Maybe switching to a different registrar is worth considering?
