The Sender Policy Framework (SPF) is an authentication mechanism used to verify the sender of an email. Internet Service Providers can use an SPF record to verify that a mail server is allowed to deliver email for a given domain. An SPF record is a DNS TXT record that lists the IP addresses that are permitted to send emails on your domain's behalf.
To authorize iCIMS as an authentic email sending source for your domain, you will need to add an SPF record for iCIMS.
Adding an SPF Record for iCIMS
Login to your DNS management console.
Navigate to Tools & Settings > DNS Template
You need to edit the DNS TXT record related to SPF
An SPF TXT record for iCIMS will have the following syntax:
name.domain.com TXT v=spf1 include:_spf.netblocks.icims.com -all
Publish this record in your DNS records section for your respective domain.
Note: If you don’t have an SPF record previously for your domain, simply publish the above-mentioned record to enable SPF for outgoing emails using iCIMS. If you do have an existing SPF record in your DNS, you need to modify it to include iCIMS, as shown below:
Previous SPF record: v=spf1 mx -all
Modified SPF record: v=spf1 mx include:_spf.netblocks.icims.com -all
Wait for 72 hours to allow your DNS to process changes
