Sender Policy Framework Record
The Xurrent service automatically generates email notifications when certain conditions are met. For example, when a request has been completed, an email is sent to its requester. The reply address of such email notifications is by default set to noreply@4me.com. Before changing the default reply address to an email address of your organisation’s domain, it is important to ensure that spam filters understand that the email notifications come from a server that is authorized to send emails for your organisation’s domain.
Spam filters use Sender Policy Framework (SPF) records to find out what the designated SMTP servers are for a domain. To let spam filters know that Xurrent’s mail servers are authorized to send email for your organisation’s domain, the SPF record needs to include this information. Do this by adding an SPF entry in the Domain Name System (DNS) zone for your organisation’s domain with the information given by the Xurrent app when configuring the email policy:
v=spf1 include:_spf.4me.com ~all
When a recipient email server receives a Xurrent email notification, this line of text ensures that it can validate that the email was sent from a server that is specified under the sender’s domain. The From address of the email will therefore not be considered forged.
