About this lesson
Hello Admins, remember that Google Workspace secures the cloud, but you are responsible for the hardware. I’ve listed the specific Enterprise-Grade tools we use to protect our clients' devices in the description below. 🛠️ ADMIN’S RECOMMENDED TOOLKIT 🌐 Business Domain: Get a FREE Domain with the GoDaddy Business Bundle : https://rebrand.ly/fo9lj7f 🛡️ Endpoint Security: Enterprise-Grade Protection for Your Startup (Norton) https://rebrand.ly/pxk8if7 💻 Device Guard: Total Identity & Device Protection for Small Teams (McAfee) https://rebrand.ly/31b3ag1 Hi Google Admin, An SPF record defines the mail servers and domains that are allowed to send email on behalf of your domain. Each domain can have one SPF record, but the record can specify additional servers and third parties that are allowed to send email from your domain. Receiving servers check your SPF record to verify that incoming messages appearing to be from your organization are sent from servers authorized by you. The SPF record also tells receiving servers what to do with messages after they're checked. An SPF record is a line of plain text that includes a list of tags and values. The tags are called mechanisms. The values are typically IP addresses and domain names. An SPF record is added to your domain provider in the form of a DNS TXT record. SPF records can have up to 255 characters. The TXT record file size should be no larger than 512 bytes. SPF record qualifier is an optional prefix you can add to any mechanism in your SPF record. Qualifiers tell the receiving mail server whether to consider a message authenticated when there's a match with a mechanism value, for example: v=spf1 include:_spf.google.com -all Mechanisms are checked in the order they occur in the SPF record. If a mechanism doesn’t have a qualifier and there’s a match, the default action is to pass authentication. When there's no mechanism match, the action default is neutral: the message doesn't pass or fail authentication.
