Enter the domain name and the report appears in seconds, listing the servers authorized to send email for that domain. An accurate SPF record is also required for DMARC protection. [ Talk to an Expert → ](/contact/) [ See what we make ](/products/) ## Here’s How You Can Do Mimecast SPF Check For Your Domain Email marketers often use Mimecast **SPF check** as a diagnostic tool to search for a particular domain’s SPF records. With these sophisticated tools available, it becomes easy to view the records. The [SPF record tester](/content/spf-record-tester) also carries out relevant tests for uncovering possible errors that may be present in the record. _If the mistakes remain unresolved, they might end up compromising the email delivery_. Mimecast has come up with a tool for **checking an SPF record**.

You must [create SPF records](/content/spf-record-tester/create-spf-record) following the right [SPF record syntax](/content/spf-record-tester/spf-record-syntax), along with elements like modifiers and mechanisms present in the [SPF record – all](/content/spf-record-tester/spf-records-all), include, a, etc. Once the record is ready, use the Mimecast SPF check tool for validating the record. However, _before applying the SPF record, scrutinize them for updates_. A look at any [SPF record example](/content/spf-record-tester/spf-record-example) will show you how it should look. With the Mimecast SPF check tool, one merely needs to insert the domain name in the field provided for verification. _The report comes in a few seconds_. ### How To Execute Mimecast SPF Check In Simple Steps? To execute a Mimecast SPF Check, one needs to **create the SPF record** at the outset. Given below are the steps to implement the SPF record and subsequently perform the record check on Mimecast. #### Step 1: Collect IP Addresses Through Which To Send The Emails Firstly, mark out the mail servers through which to dispatch the emails from the domain. The group includes the [mail server](https://whatismyipaddress.com/mail-server) of the ISP, in-office mail servers, web servers, and third-party mail servers. #### Step 2: List Up The Sending Domains Secondly, prepare a list containing the names of the sending domains. The organization may own several domains, but only some may be in use to send emails. Make sure to **create an SPF record** for all the domains under control. _The reason is that malicious players would also try to spoof the domains that are not used for sending emails_. #### Step 3: Create The SPF Record The third step involves the creation of the SPF record, authorizing the legitimate senders. Remember, _SPF records cannot exceed 255 characters_. Besides, the number of additional [DNS lookups is limited](https://docs.sendgrid.com/ui/account-and-settings/spf-limitations) to ten. #### Step 4: Publishing SPF To DNS In this step, get the SPF record published to DNS. It would enable the mailbox providers to reference it. The process becomes simple with Mimecast. #### Step 5: Perform The Mimecast SPF Check Use the Mimecast SPF check tool for testing the record. At this stage, the user can view precisely what the recipients see. It should include a list of servers that have been authorized to dispatch emails on behalf of the sending domain. ![create spf record](https://media.mailhop.org/duocircle/images/2021/07/create-spf-records.png)![spf record example](https://media.mailhop.org/duocircle/images/2021/07/spf-record-checker-tool.png) ### What Makes Mimecast SPF Check Necessary For DMARC Protection? _Email authentication protocols involve DMARC, which would only function properly with the accurate setup of SPF and DKIM_. One might use the tool launched by Mimecast or even other options, like the [SPF record check Google](/content/spf-record-tester/spf-record-check-google) to implement the record check. Next, when using the DMARC analyzer, one will obtain detailed information through a report regarding who is dispatching emails on behalf of the organization. ### DMARCreport.com – An Alternative To Mimecast For a seamless **SPF record resting**, one can use a robust tool such as the Mimecast SPF check or [Kitterman SPF](/content/spf-record-tester/kitterman-spf) tester.
