To start using your domain with your newly purchased business email service, you need to ensure that your domain has the proper DNS records first.

Where should I point my MX Records?

Below is a list of all the Business Email Services MX records information. All have the same priority. We recommend adding them all for maximum resilience. Ensure NO other MX records are currently present in your domain DNS apart from these.

Name/Host/Alias Record Type Priority Value
@ or leave blank MX 10 mx001.cloudus.xion.oxcs.net
@ or leave blank MX 10 mx002.cloudus.xion.oxcs.net
@ or leave blank MX 10 mx003.cloudus.xion.oxcs.net
@ or leave blank MX 10 mx004.cloudus.xion.oxcs.net

What SPF records should I use?

Below are the SPF records you will need to set to have your email work with the Business Email Services.

Name/Host/Alias Record Type Value
@ or leave blank TXT v=spf1 include:spf.cloudus.rs.oxcs.net ~all

What DMARC records should I use?

To deploy DMARC, you must publish a DMARC record in DNS for your domain.

An example DNS TXT DMARC record should follow the format.

v=DMARC1; p=quarantine; rua=mailto:[email protected]; ruf=mailto:[email protected];

Replace yourdomain.com with your domain name.
