Overview

TrekkSoft sends emails like confirmation emails, pre-trip emails, post-trip emails, etc. to the end customer on behalf of the merchant's custom email address, but the email delivery may fail due to incorrect setup of the SPF record. Here in this article, we'll explain to you how to setup the SPF records correctly so that each email that TrekkSoft sends to your customers delivers to them successfully.

What is DNS SPF record

A sender policy framework (SPF) record is a type of DNS TXT record that lists all the servers authorized to send emails from a particular domain.

A DNS TXT (“text”) record lets a domain administrator enter arbitrary text into the Domain Name System (DNS). TXT records were initially created for the purpose of including important notices regarding the domain, but have since evolved to serve other purposes.

What does an SPF record look like?

SPF records must follow certain standards in order for the server to understand how to interpret its contents. Here is an example of the core components of an SPF record:

v=spf1 ip4=192.0.2.0 ip4=192.0.2.1 include:examplesender.email -all

This example lets the server know what type of record this is, states the approved IP addresses and a third-party for this domain, and tells the server what to do with non-compliant emails.
