DNS, MX records and related info
There is no charge for hosting the DNS for your domain and we're happy to do it. Normally when we host the DNS we host both the email and web site for your domain. You need to let us know whether we'll be hosting your DNS.
If Webville will be hosting your domain and providing the name servers (DNS), you will need to give your domain name registrar (GoDaddy, etc.) the following information:
If your domain is registered with GoDaddy, the following steps and the screen shot should help you, but they change their site all the time so it may be different now. If your domain is with another registrar, it will be similar to this.
Log in at the GoDaddy web site, click My Account, click the Manage button next to Domains, then click on the particular domain you want to manage (if you have more than one), in the Nameservers section click Manage. Something like the screen shot below will appear. Choose Custom name servers, remove any other name servers (if any) and add ours as listed above and shown in the screen shot. When you're finished you should have just our two name servers -- no other name servers. Click the thumbnail for full size image.
If Webville hosts the DNS (name servers) for your domain name we will create the appropriate MX records in the DNS zone for your domain. If your DNS is hosted elsewhere, you need to create the MX record.
This must be the only MX record present in your configuration. Remove any other MX records and create this one. Once your domain is up and running with this MX record, we'll obtain MX records from Barracuda which allow you to benefit from the Barracuda Cloud Protection Layer. You will then need to implement those MX records. Going forward your MX records will resemble xxxxxx.ess.barracudanetworks.com where the xxxxxx is a unique identifier for your domain.
If Webville hosts the DNS (name servers) for your domain name we will create the appropriate AutoDiscover configuration in the DNS zone for your domain. If your DNS is hosted elsewhere, you need to create the AutoDiscover record.
A properly configured AutoDiscover host record is required.
The simplest test of the autodiscover host record is from a command prompt on your computer as follows: nslookup autodiscover.yourdomain.comIt should immediately return the address 18.104.22.168. If it does not, shoot a screen shot of the results and send to us for review.
Microsoft's Remote Connectivity Analyzer is a great tool. It's detailed results can pinpoint the issue if your domain is misconfigured. https://testconnectivity.microsoft.com/
Autodiscover requires that your web site and its security certificate are configured properly. The most common failing we see lately is a site that responds to https requests with a bad certificate. If the site responds to https requests at all, it must respond with a valid certificate from one of the big certificate providers (not a self-generated certificate). Websites with catch-all error pages also disrupt AutoDiscover. Contact us for further details if necessary and/or review the details at the link:
Sender ID (SPF TXT record)
If Webville hosts the DNS (name servers) for your domain name we will create the appropriate SPF configuration in the DNS zone for your domain. If your DNS is hosted elsewhere, you need to create the SPF record.
SPF records designate the servers which are authorized to send outbound email for your domain. Here is a short, simple SPF record you could use if our servers will be sending all outbound email for your domain:
v=spf1 ip4:22.214.171.124/26 ?all
If you will be using a mailing service such as Constant Contact, or a help desk ticket system, or any other third party system which needs to send email purporting to be from your domain, the SPF record needs to include that. We'll help you figure it out.
See the following for more about configuring Sender ID and SPF records:
Skype for Business (formerly Lync)
If Webville hosts the DNS (name servers) for your domain name we will create the appropriate Lync configuration in the DNS zone for your domain. If your DNS is hosted elsewhere, you need to create the Skype/Lync records.
Properly configured Skype/Lync records are not optional. This must be configured correctly or users will get multiple errors and loss of funtionality in Outlook and Skype/Lync.
OWA (Outlook Web App) Shortcut (Optional)
If we host the DNS for your domain, we'll take care of this for you and create the appropriate record for your domain. If the DNS is hosted elsewhere, the OWA shortcut can be created as follows. This is an optional record purely for convenience of accessing an easily remembered URL for OWA.
When this record is configured properly in the DNS for your domain name, you can easily to go owa.yourdomain.com in your web browser and automatically be redirected to the login page for Outlook Web App.
Splitting up the email and web hosting for a domain
Yes, you can have your web site hosted with one provider and your email with another provider. A lot of our customers do that. They're happy with their ISP, and the ISP hosts the web site. But the ISP does not offer Exchange Hosting, so the ISP simply changes the DNS MX records and SPF records for the domain, and the incoming email for the domain comes here to our Exchange servers.
Domain sharing - hosting some of the users @ yourdomain.com
Yes, you can migrate users to our service gradually. This is accomplished by forwarding their incoming mail from your old server to their @webville.net address.
We can make the reply addresses on your mailboxes @yourdomain.com to keep up the desired appearance, while the mailboxes also have secondary addresses @webville.net to receive the forwarded mail.
Contact us for more details and to discuss individual situations.
The Domain Name System (DNS) is a constant source of... well... interest, to systems people. But let's say you're not a network engineer, you're just a guy with a web site and email for his domain name, and you're interested in using Exchange Hosting Service. What do you really need to know?
Basically, all domain names are registered with the central Internet authority that operates the so-called root servers. Your domain name is registered with them. They have a record for your domain that provides the addresses of two or more DNS servers which are responsible for your domain.
Those DNS servers have several records relative to your domain. They have "host" records which give IP addresses for named computers within the domain. For example, a couple of host records might look like this:
www.company.com. IN A 127.127.127.127mail1.company.com. IN A 127.127.127.128mail1.company.com. IN A 127.127.127.129mail2.company.com. IN A 127.127.127.130
Basically, the www record tells web browsers where to go to find your web site. But the mail is a little more complicated. It depends on the MX record or records. They might look like this:
company.com. MX 10 mail1.company.com.company.com. MX 20 mail2.company.com.
Those records tell email servers on the internet where to go when they want to send mail to someone at your domain.
MX Preference Settings Explained
When there are two MX records, the preference number is a way to set priority between multiple mail servers for a domain. The lower number is the higher priority. Servers with the higher priority numbers are supposed to be contacted only if servers with lower priority numbers are unavailable. Spammers have corrupted this practice by going to higher preference numbers hoping to reach unfiltered and/or vulnerable servers. The system was intended to allow providers to build in redundancy and let mail flow automatically through backup systems if -- and only if -- primary systems are unreachable.
So understanding all of that, you see how we can host the email for your domain while the web site stays put right where it is.
Of course, we can also host the web site and the DNS for the domain, if you like. We have nothing against web hosting! This business started out doing web hosting in 1997 - hence the name Webville.net. We've just found that a number of our customers are happy with their current web hosting provider and curious about whether they can use Exchange Hosting Service for their email without disrupting the web hosting. The answer is yes, you can.
To test the DNS for your domain name, use the "NSLOOKUP" tool, available from the command prompt of Windows machines. Type the following at a C:\ prompt:
Autodiscover.yourdomain.com should immediately return the address 126.96.36.199The MX records should be something like xxxxxx.ess.barracudanetworks.comIf you're unsure, please take a screen shot of the results and send it to us for review. Type exit to leave nslookup and return to the command prompt. Type a "?" at the nslookup prompt to find out more about what the nslookup tool can do.
