How to set up an SPF record for CR Servers hosting
Publish an SPF TXT record so receiving servers know which hosts may send mail for your domain.
SPF (Sender Policy Framework) is a DNS TXT record that lists servers allowed to send mail for your domain.
Typical SPF for mail on CR Servers hosting
Create a TXT record on the domain apex (@ / yourdomain.com):
v=spf1 a mx include:crservers.com ~all
Your welcome message or support may give a more specific include: value for your server. Prefer one SPF TXT record — do not publish multiple conflicting SPF strings.
After publishing
Wait for DNS TTL to expire, then validate with an SPF lookup tool. Pair SPF with DKIM and DMARC.
