You can use a вЂњ-вЂќ which means that all emails will fail SPF checking if they match вЂњallвЂќ. You can use a вЂњ+вЂќ which means that all emails will pass SPF checking, you probably donвЂ™t want this as unauthorized emails would be marked as valid. There are a few values that can be used instead of the вЂњ~вЂќ. The вЂњ~вЂќ before вЂњallвЂќ says that an email that matches вЂњallвЂќ will be marked as a soft failure. So if the email is sent through another email server that isnвЂ™t listed, then itвЂ™s processed by the вЂњallвЂќ record. The values within the SPF record are processed in the order listed. The final part is the вЂњ~allвЂќ section of the record. Again, since you canвЂ™t send email as someone elseвЂ™s domain without verifying that itвЂ™s your domain, we can trust this setup. The вЂњinclude:вЂќ section is the SPG section for SendGrid.

The вЂњinclude:вЂќ section is the SPF section for MailChimp. As Office 365 will send all emails from severs that come back to that DNS name, this marks all the records as valid and since you canвЂ™t send email through Office 365 without authenticating, we can trust this setup. This section says that any emails that are sent from Office 365вЂ™s outbound email servers are valid. The вЂњinclude:вЂќ section is the SPF section for Office 365. QuickBooks Online uses a bunch of outbound email servers, and they are all contained within the three subnets listed. If version 2 of SPF comes out, then this would need to be changed to that. The вЂњv=spf1вЂќ part says that this is SPF version 1. Let me explain how this specific record works. This all needs to be added to our SPF record so that emails sent by any of these services are marked as valid from an SPF perspective. In the case of DCAC, we use Office 365 as well as SendGrid, QuickBooks Online, and MailChimp. To add this in, you first need to know what servers will be sending emails for your domain. This record is a text record at the root of the domain. ThereвЂ™s a couple of different records that need to be created. When the emails are then received by the receiving email server, it checks these DNS records against the email that was just received to see if the email was sent from an SMTP server that is listed in the DNS record. This involves setting a few DNS records in the DNS domain for that company. One of the ways that companies can help others ensure that emails are coming from where they claim to be coming from, is to set up outbound email security. Anyone can send email as another person, which is one of the reasons that we have junk email. Email is the wild wild west of the internet.
