In order to send emails from RMS Cloud, you may need to make some changes to your email domain's SPF (Sender Policy Framework) entry. This change may require assistance from the person or company that manages your domain name registration and/or website hosting.
SPF is an email validation system employed by many mail servers around the world. It allows the administrator of a particular domain name to specify the IP addresses that other mail servers should expect to receive email from for their domain name.
If you have enabled SPF on your domain but have not included the RMS Cloud mail servers in your policy, then some mail servers will reject any email messages sent out from RMS.
RMS Recommends that you add an 'include' entry to your SPF record which will then include all of the IP addresses that RMS lists in our SPF record. This means that if we add new servers or make changes to our network at a later stage, you will not have to change your SPF record again.
So for example, if your current SPF record looks like this:
yourdomain.com descriptive text "v=spf1 mx ip4:xxx.xxx.xxx.xxx/32 ~all"
The updated SPF record would look like the following (note the addition in bold):
yourdomain.com descriptive text "v=spf1 mx ip4:xxx.xxx.xxx.xxx/32 include:rms.com.au ~all"

RMS only recommends following this article if you already have an SPF record on your domain and you clearly understand how the technology works. There is no requirement to have SPF enabled on your domain in order to use RMS Cloud.
