This instructional article will demonstrate the  Mimecast <\/em>configuration process of Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM) Signatures to ensure Mimecast <\/em>passes the DMARC alignment check and eliminates spam from your domain and increases security.<\/p>\n\n\n\n

The SPF record identifies the mail servers and domains that are allowed to send email on behalf of your domain. The DKIM record, on the other hand, is a specially formatted DNS TXT record that stores the public key the receiving mail server will use to verify a message’s signature. These email authentication methods will be used to prove to ISPs and mail services that senders are truly authorized to send email from a particular domain and are a way of verifying your email sending server is sending emails through your domain.<\/p>\n\n\n\n

The process of setting up the SPF record<\/strong><\/h2>\n<\/div>\n<\/div>\n\n\n\n

To ensure the emails from Mimecast are sent on behalf of your domain, we need to create or update your existing SPF record by including the following information.<\/p>\n\n\n\n

Field \/ Option<\/strong><\/td>Description<\/strong><\/td><\/tr>
Europe (excluding Germany)<\/td>include:eu._netblocks.mimecast.<\/strong>com<\/td><\/tr>
Germany<\/td>include:de._netblocks.mimecast.<\/strong>com<\/td><\/tr>
United States of America<\/td>include:us._netblocks.mimecast.<\/strong>com<\/td><\/tr>
Canada<\/td>include:ca._netblocks.mimecast.<\/strong>com<\/td><\/tr>
South Africa<\/td>include:za._netblocks.mimecast.<\/strong>com<\/td><\/tr>
Australia<\/td>include:au._netblocks.mimecast.<\/strong>com<\/td><\/tr>
Offshore<\/td>include:je._netblocks.mimecast.<\/strong>com<\/td><\/tr>
Global (includes all the above)<\/td>include:_netblocks.mimecast.<\/strong>com<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

As listed in the information above, check your server location and add the Include: mechanism in your SPF Record. For this example, we\u2019ll be using the Europe option.
