This article details the DNS records that are required for you to use our Hosted Exchange service. These settings only apply to hosted exchange customers. For standard hosting customers, see the standard mail server settings.
MX Records are part of a domain's DNS record that tells other mail servers on the Internet where messages addressed to a domain should be delivered to.
To change MX records, you may need to contact the domain hosting company or the owner of the domain. If you registered the domain through Calzada Media, contact our support team.
The following MX records are required for the hosted exchange service:
IMPORTANT - Please ensure that these are the only MX records applied to a domain name on our Exchange platform. If not, email will randomly pass into any other listed mail servers and not be delivered correctly, even if they're listed on a higher preference. In fact, those that distribute spam often pick the MX record with the highest preference in the hope that this route will have less spam protection.
The CNAME 'AutoDiscover' entry is needed for Exchange 2013 and Outlook to function properly together. It helps both with the quick configuration of Outlook, but also smartphones and other similar devices.
To add a CNAME record, you may need to contact the domain hosting company or the owner of the domain. If you registered the domain through Calzada Media, contact our support team.
The CNAME record that should be created is:
So, if your domain is greenfields.com, the CNAME record will be autodiscover.greenfields.com
The last DNS entry that is required is the SPF, or Sender Policy Framework record. SPF is a significant and increasingly used method to protect against spam sent from forged addresses.
SPF is used to confirm that a message actually has been sent from a mail server that has the authority to send the e-mail. If no SPF records are in place, e-mails may be scored with a high spam probability.
To add the SPF record, you may need to contact the domain hosting company or the owner of the domain. If you registered the domain through Calzada Media, contact our support team.
If your domain does not have a SPF DNS record, then the SPF record should resolve to:
If your domain already has an SPF record, then you need to add include:spf.cloudplatform1.com into the current record before the "-all" part of the syntax. For example:
