For setting up the SPF settings in your server all you need to follow is the below steps which are as follows:
Stage 1: Collect the IP addresses which are required to send emails
The initial step to actualize SPF is to recognize which mail servers you use to send email from your particular server. Numerous associations send emails from an assortment of locations.
Make a rundown of all your email servers, and make sure to consider whether any of coming up next is utilized to send email for your business brand as Web server, In-office mail server such as Microsoft Exchange, ISP’s email server, The mail server of your final clients’ the provider of mailbox, The email server of the this party which are used to send emails on the behalf of your particular brand.

In the case, if your business is having more than one domain. Whereas some of the domains are utilized to send emails only.
It is imperative to make SPF records for all of your domains for the company. Even for those also which are not used to send emails.
It is because once you have secured your sending domains with the SPF, the main thing a hacker will do is endeavor to spoof of the domains which are not used to send emails.
Stage 3: Then make your SPF record
SPF verifies the identity of the sender by looking at the sending emails server’s IP addresses with the list if the approved or authorized sending IP addresses which are published by your sender into the DNS record. Now follow the stages to make you make SPF record:
Begin with v=spf1 tag and then follow the same with the IP addresses that are approved to send emails. For instance, v=spf1 ip4:220.127.116.11 ip4:18.104.22.168
In the event that you utilize a third party so to send the email on the behalf of the domain being referred to, then you need to add up an “include” explanation in your SPF record to assign that the third party is the legitimate email sender and allow them to send emails.
When you have included all approved or authorized IP addresses and incorporate explanations, end your record with a ~all or – all tag
A ~all tag shows a delicate SPF fail while a – all tag demonstrates a hard SPF fail. According to the significant mailbox suppliers ~all and – all will both outcome in SPF failure. Return Path prescribes a – all as this is one of the most reliable and safe records to maintain.
SPF records can’t be more than 255 characters long and cannot include in excess of ten incorporate proclamations, otherwise called “lookups.” Here’s a case of what your record may resemble:
v=spf1 ip4:22.214.171.124 ip4:126.96.36.199 include: thirdparty.com – all
For the domains that don’t send email, the SPF record will prohibit any modifier except for – all. Here’s a model record for the particular domain which is not used to send emails:
v=spf1 – all
Thus now you are all done, yes your SPF is created now and it’s the final time to publish or test the same.
