Not sure if this goes here or on serverfault, but here it goes. I have an account with Fastmail where I host my email. So my domain ( currently resolves to that, including WWW as well (they have that option). The domain is registered with godaddy, and the name servers there are the Fastmail ones.

Now, I want to host on Arvixe but I've never done separate DNS resolution (if that's the term); I'd like to host a website with them but keep my email with FastMail. I was wondering if that's more easily accomplished through godaddy, or assuming a standard DNS configuration screen, how would I forward A record queries to Arxive and MX queries to Fastmail.

You can't forward queries like that – you will need to configure the records on your domain directly, setting the A records to Arvixe's IP addresses (given by Arvixe) and the MX records to's mail servers. The configuration is more-or-less the same regardless of where your domain is hosted.

Since your domain is currently hosted on's DNS servers, you can change the A records using the domain management interface (Options → Custom DNS or Manage → Custom DNS) and keep the MX records with their current values. See the domain management & setup page on

I have never used their DNS management interface, but the end result should look similar to this:              MX      10              MX      20              A              A          A          A

(Since Arvixe's support pages do not mention their web servers' addresses anywhere, I used and as examples. The mail servers of are real and were taken from this page.)

Note that and are independent in terms of DNS records. For a website, you will probably want to add identical A records to both domains. (However, for mail, MX records on usually are not necessary.)

Thank you for the detailed information! I will give this a go tonight when I get home. – kprobst May 23 '12 at 19:04
Ah, stupid me - this answer only explains incoming SMTP setup, not IMAP... But on the other hand, IMAP doesn't actually need to be set up - just connect to instead. – grawity May 23 '12 at 19:30
My god that worked... thank you again! – kprobst May 25 '12 at 16:38

If you want to send an e-mail to support [@] with your Arvixe user name we will be able to provide you the IP addresses for your server for the A records.
