How can I enter a spf record?
What is SPF?
SPF Records (Sender Permitted From or Sender Policy Framework) are entries that specify which mail servers are allowed to send e-mails from your domain. Thus, SPF prevents the circulation from e-mails that have your sender address but are not from you.
Providers that support these entries are able to detect this common type of spam e-mails and treat them accordingly.
A typical SPF record for the domain key-systems.net is for example:
"v=spf1 a:mail.key-systems.net -all“.
Configure SPF record
If you want to use such an entry please configurate your domain by entering a SPF record. For doing so, please go to Expert Mode Advanced settings TXT record, enter your SPF record and save it.
