TAGTAG DESCRIPTION
v (required)The version tag. is the only allowed value is "spf1". If it's incorrect or the tag is missing, the SPF record will be ignored.
ip4This tag should include all the IPv4 addresses that are allowed to send emails on behalf of the domain.
ip6This tag should include all the IPv6 addresses that are allowed to send emails on behalf of the domain.
aThe A record tag allows the SPF to validate the sender by domain name's IP address. If left unspecified, it takes the value of the current domain.
mxThe MX record tag checks the MX record of the mail server(s). If left unspecified, it takes the value of the current domain.
ptr (Not recommended)The PTR tag prompts a PTR check for client IP hostname(s). It's a not recommended tag as per RFC 7208, because it spends too many DNS lookups.
existsThe exists tag checks if an A record exists or not on the mentioned domain.
includeThe include tag is of top importance for a correct SPF record. Listing all your sending sources under this tag lets the recipient know that you verify all the aded domains/subdomains as legitimate sources.
all (required)All is a required tag. It should be placed at the end of the SPF record. Depending on the qualifiers used (~, +, -, ?), this mechanism indicates how the recipient should treat emails from non-authorized sources.
