Configuring email dispatching with CentrixOne:

For CentrixOne to be able to send emails in your name (i.e. using your email address) you need to give CentrixOne permission to connect to your email domain name.

You should note that all the bits of code that are provided here have to be typed exactly as presented (of course, that does not apply to "", which has to be replaced by your own domain name). Each and every single underscore, point, dash sign, etc have to be typed perfectly. DNS records are case sensitive.

Important notice: Some registrars or web hosts automatically add the domain name at the end of DNS records. In that case, you must not replace "" with your actual domain name, but rather simply leave it blank. Therefore, "" would become "s1._domainkey".

To do this you need to modify and/or add some information to your domain's DNS. The steps are outlined bellow:

1 - Add to the TXT record beginning with v=spf1, located at the root of your domain.

Example of a domain that does not already have a SPF record:

v=spf1 mx ~all

Be advised that you may already have a SPF record. This may be because you’ve already given similar permissions to other apps (such as Outlook) to use your domain name. In this case, you need to make sure not to create a new SPF record, but to instead edit the existing one.

See the example below:

If you already have somethingsuch as :

v=spf1 mx -all

You'll have to add a new "include" sub-record. It should look something like this:

v=spf1 mx -all

2 - Add a CNAME record named s1._domainkey pointing to



If you need more information on the SPF, you can visit this page.

3 - Add a CNAME record named s2._domainkey pointing to



4 - Add a CNAME record named pointing to



Important: Please inform us via email at when the changes have been made so that we can activate and associate the domain name with your CentrixOne account.
