Below is the syntax for SPF record :<\/strong><\/p>\n

Example: v=spf1 a mx ip4:192.168.0.1 include:spf.example.com -all<\/p>\n\n\n\n\n\n\n\n\n
V<\/th>\nversion<\/th>\nThe SPF record version<\/th>\nDescription<\/th>\n<\/tr>\n
a<\/td>\n\u00a0<\/td>\nPass<\/td>\nMatch if IP has a DNS ‘A’ record in given domain .<\/td>\n<\/tr>\n
mx<\/td>\n\u00a0<\/td>\nPass<\/td>\nMatch if IP is one of the MX hosts for given domain name<\/td>\n<\/tr>\n
IP4<\/td>\n198.164.0.1<\/td>\nPass<\/td>\nMatch IP address<\/td>\n<\/tr>\n
include<\/td>\nexample.com<\/td>\nPass<\/td>\nThe specified domain is searched for an ‘allow’<\/td>\n<\/tr>\n
-all<\/td>\n\u00a0<\/td>\nFail<\/td>\nAlways matches. It goes at the end of your record<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

having a valid and accurate SPF record will lead to improved authentication coverage, deliverability and help promote your desired level of security for your domains.
Mechanisms:
all
ip4
ip6
a
mx
ptr
exists
include<\/p>\n

 <\/p>\n

Mechanisms can be used to describe the set of hosts which are designated outbound mailers for the domain and can be prefixed with one of four qualifiers:
+ (Pass)
\u2013 (Fail)
~ (SoftFail)
? (Neutral)
The default qualifier is ‘+’, i.e. ‘Pass’.Mechanisms are evaluated in order. If no mechanism or modifier matches, the default result is \u201cNeutral\u201d.If a domain has no SPF record at all, the result is ‘None’. If a domain has a temporary error during DNS processing, you get the result ‘TempError’. If syntax or evaluation error occurs (eg. the domain specifies an unrecognized mechanism) the result is ‘PermError’.<\/p>\n


Evaluation of an SPF record can return any of these results:

<\/p>\n\n\n\n\n\n\n\n\n\n\n
Result<\/th>\nExplanation<\/th>\nIntended action<\/th>\n<\/tr>\n
Pass<\/td>\nThe SPF record designates the host to be allowed to send<\/td>\naccept<\/td>\n<\/tr>\n
Fail<\/td>\nThe SPF record has designated the host as NOT being allowed to send<\/td>\nreject<\/td>\n<\/tr>\n
SoftFail<\/td>\nThe SPF record has designated the host as NOT being allowed to send but is in transition<\/td>\naccept but mark<\/td>\n<\/tr>\n
Neutral<\/td>\nThe SPF record specifies explicitly that nothing can be said about validity<\/td>\naccept<\/td>\n<\/tr>\n
None<\/td>\nThe domain does not have an SPF record, or the SPF record does not evaluate to a result<\/td>\naccept<\/td>\n<\/tr>\n
PermError<\/td>\nA permanent error has occurred (eg. badly formatted SPF record)<\/td>\nunspecified<\/td>\n<\/tr>\n
TempError<\/td>\nA transient error has occurred<\/td>\naccept or reject<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
