SPF exists to prevent spammers from forging the identity of the sender of an email message. Sender Policy Framework (SPF) allows the receiving mail server to check during mail delivery that mail claiming to come from a specific domain is submitted by an IP address authorized by that domain's administrators. The list of authorized sending hosts and IP addresses for a domain is published in the DNS records for that domain.
Vuture doesn’t use just one SPF record mechanism, but several that are appropriate for your region. They are as follows:
include:spf-uk.vx-email.com
include:spf-us.vx-email.com
include:spf1-apac.vx-email.com
include:spf1-ca.vx-email.com
Or, you can also use a single include segment that includes all the above-mentioned mechanisms, which is:
include:spf.vx-email.com
Note: You can either publish the SPF record as a new record or include it as a part of your previous SPF record, by modifying it.
Finally, check if your SPF record is valid and functional by using our SPF record lookup tool
