SPF
SPF (Sender Policy Framework) ensures that a customer in Survey from his own domain can email. SPF is a setting that must be performed by the customer in their own domain's DNS settings. Ask at info@crowdtech.com to the manual to set the SPF.
DKIM
An additional step that is recommended is the implementation of DKIM (DomainKeys Identified Mail). This checks whether the e-mails are actually belong to a particular domain. DKIM is set up in two steps:
- as a customer, add the DKIM in your domain's DNS settings;
- Crowdtech will also set up the DKIM at the mail provider after this implementation.
So make sure that there is both an action in the domain of the customer and at Crowdtech is needed. Without this collaboration, sending e-mail can be a problem. So explicitly request Crowdtech to enable the DKIM signing. Question at info@crowdtech.com to the manual to set the DKIM.
DMARC
If you have set up SPF and DKIM you can optionally use DMARC (Domain-based Message Authentication, Reporting and Conformance). This is an optional step for additional email security. Please note that after setting up the DMARC . Crowdtech no more bouncers processed. You have to process the bouncers yourself via a mailbox in your own domain. Contact info@crowdtech.com for advice.
